	Title	Thermal Analysis of the Cadmium and Manganese Hydrogen Orthoarsenate Monohydrates (M HAs04 * H20, where M = Cd, Mn)
	Abstract	The dehydration decomposition of cadmium and manganese hydrogen orthoarsenate monohydrates was studied by static isothermal and differential thermoanalytical methods. It was found that the dehydration decomposition takes place in a single stage forming the respective diarsenate, the peak minimum temperature being 458 K for the cadmium and 466 K for the manganese salt.

	Title	Synthesis, Structure, and Magnetic Properties of EuAgCd and YbAgCd
	Abstract	New intermetallic compounds EuAgCd and YbAgCd were synthesized in quantitative yield by reaction of the elements in sealed tantalum tubes in a high-frequency furnace. Both com pounds were investigated by X-ray diffraction on powders and single crystals: KHg2 type, Imma, a = 490.41(8), b = 771.0(1), c = 834.4(2) pm, wR2 = 0.0624, 255 F values, 12 variables for EuAgCd, and MgZn2 type, Pb^/mmc, a = 584.66(5), c = 946.83(9) pm, wR2 = 0.0502, 187 F 2 values, 11 variables for YbAgCd. Owing to the very small difference in scattering power, no long range ordering of the silver and cadmium atoms is evident from the X-ray data, although Ag-Cd ordering is expected. The silver and cadmium atoms randomly occupy the mercury and zinc positions of the KHg2 and MgZn2 type structures, respectively. In EuAgCd the [AgCd] substructure consists of strongly puckered, orthorhombically distorted Ag3 Cd3 hexagons, while a three-dimensional network of face-and comer-sharing tetrahedra is observed in YbAgCd. The rare earth atoms fill the space between the Ag3 Cd3 hexagons (EuAgCd) or within the three-dimensional tetrahedral network (YbAgCd). Magnetic susceptibility measurements in dicate Pauli paramagnetism for YbAgCd and Curie-Weiss behavior above 60 K for EuAgCd with an experimental magnetic moment of 7.82(3) /j b/Eu indicating divalent ytterbium and europium. Ferromagnetic ordering at Tc = 28.0(5) K is observed for EuAgCd. At 2 K and 5 T the saturation magnetization is 5.85(5) /iß/Eu.

	Title	The Endoplasmic Reticulum Chaperone G RP94 Is Induced in the Thyrocytes by Cadmium
	Abstract	We established a relationship between the toxic effects of cadmium on the expression of the endoplasmic reticulum (E R) chaperone GRP94 (glucose regulated protein 94) and cell survival in cultured rat-thyrocytes of FRTL5 cells. There are no data reporting that the en hanced expression of G RP94 by Cd stimulation is detectable in thyrocytes. Western blot analysis revealed higher levels of GRP94 expression in those cells post-treated with low concentrations of Cd, following a step-down treatment method, than in Cd pre-treated cells or cells not treated with any Cd, due to changes in cellular sensitivity after pre-treatment with Cd and the possible induction of G RP94 expression after removal of a low concentration of Cd. Elevated G R P94 expression in thyrocytes post-treated with Cd confers a survival advantage by rendering them resistant to cytotoxic stress, and the existence in the thyrocytes of a Cd-specific pathway regulates the expression of stress proteins by Cd.

	Title	Cadmium against Higher Plant Photosynthesis -a Variety of Effects and Where Do They Possibly Come From?
	Abstract	2 0 -0 3 3 Lublin, Poland. Fax: (48-81) 5 3 7 5 1 0 2 . E-mail: zkrupa@biotop.umcs.lublin.pl The complexity of in vivo toxic effects of Cd on higher plants makes almost impossible an accurate distinction between direct and indirect mechanisms of its action on the photosyn thetic apparatus. We, therefore, postulate that multiple Cd effects on plant physiological and metabolic processes may finally be focused on photosynthesis. This would also explain the phenomenon that only a small fraction of Cd entering chloroplasts may cause such disastrous changes in their structure and function. In return, the inhibition of photosynthesis affects numerous metabolic pathways dependent on the primary carbon metabolism.

	Title	Cd0,73 Cu0,27V2 O 6: A Com pound with Brannerite Structure
	Abstract	Single crystals of Cd() 73Cu<,.27V 20 6 were prepared by solid state reactions. X-ray investiga tions lead to monoclinic symmetry, space group C \h-C2lm , a = 9.339, b = 3.5604, c = 6.893 A , ß = 111.85°, Z = 2. It belongs to the Brannerite structure, showing a statistical distribution of Cd2+ and Cu2+ on one point position. The crystal structure of Brannerites is discussed with respect to the distorted O 2-octahedra around V 5+ and the influence of the Jahn-Teller active Cu-+ ion to the shortened M2+Oa octahedra.

	Title	Zur Synthese und Kristallstruktur von Kupfercadmiumpyroboratoxid: Cu2Cd(B20 5) 0 Synthesis and Crystal Structure of Copper Cadmium Pyroborate Oxide: Cu2Cd(B20 5) 0
	Abstract	Single crystals of the new compound Cu2C d(B20 5) 0 have been prepared by B 20 3/V 20 5 flux technique in a closed silver tube. Their structure is isotypic with Cu2C o(B 20 5) 0 but its preparation is quite different. X-ray investigations on single crystals led to the space group C \|h-P 2 !/c (Nr. 14), a = 339.9(2); b = 1509.8(2); c -927,0(1) pm; ß = 93.19(1)°; Z -4. The structure contains isolated B 2O s groups and oxygen that is not coordinated to boron. Cad mium is octahedrally coordinated by oxygen, while copper exhibits a nearly square planar or a fivefold pyramidal coordination.

	Title	Synthese und Struktur von Zn(HS0 4)2(H2S0 4)2 und Cd(H S04)2 Synthesis and Structure of Z n(H S04)2(H2S 0 4)2 and C d(H S 04)2
	Abstract	From the binary systems M2S 0 4/H2S 0 4 (M = Zn, Cd), two new hydrogen sulfates, (Zn(HS0 4)2(H2S04)2 and Cd(HS04)2, have been synthesized and structurally characteri zed. Both compounds crystallize in the monoclinic space group P2,/c with cell parameters a = 5.047(2), b = 15.430(4), c = 7.958(3) A and ß = 104.16(4)° (Z= 2) for Zn(HS04)2(H2S 0 4)2 and a = 5.339(1), b = 13.351(3), c = 8.508(2) A and ß = 92.22(3)° (Z = 4) for Cd(H S04)2. In the zinc compound there are slightly distorted centrosymmetric Z n 06 octahedra with Z n -0 distances of 2.05 -2.13 A which are sharing corners with S 0 4 tetrahedra. H S 04 and H2S 0 4 tetrahedra are linked via hydrogen bonds to form layers perpendicular to the c-axis. In the crystal structure of C d(HS04)2there exist two crystallographically different H S 04 tetrahedra. The C d06 octahedra with C d -0 distances between 2.24 and 2.31 A are strongly angle-distorted. Besides hydrogen bonds of medium strength (d0...o = 2.66 A) there are also much more weaker ones (d0...0 = 3.04 A). Considering these latter ones zigzag chains in z-direction can be recognized. The relatively low stability of Cd(H S04)2 in comparison with other metal-II-hydrogen sulfates is discussed with respect to its structural pecularities.

	Abstract	Single crystals of Ba2 ^C di^V O ^g have been prepared by solid state reactions. The new compound crystallizes with orthorhombic symmetry, space group D ^-Pbcn, a = 20.842(6), b = 13.471(3), c = 11.838(9) A, Z = 4. The crystal structure is characterized and dominated by C d 0 6 octahedra and unusual square pyramids of 0 2~ around Cd2+ forming a three-dimensional [C d ]\|0 36] network. The interstices are occupied by V 5+ and Ba2+ ions. This results in V 0 4 tetrahedra and irregular BaO 10 polyhedra isolated from each other. Occupation of the barium positions is deficient in agreement with the valence state V5+ and calculations of the coulomb terms of lattice energy.

	Title	Reaktionen des donorfreien (C F 3 )2Cd mit Phosphor(V)halogeniden: Difluorcarben-Einschiebungen und Direktsynthese von (C F 3)3PF2 Reactions of Donor-Free (CF3)2Cd with Phosphorus(V) Halides: Insertion of Difluorocarbene and Direct Synthesis of (CF3)3PF2
	Abstract	Difluorocarbene which is quantitatively eliminated from donor-free bis(trifluoromethyl)-cadmium below 0 °C inserts smoothly into the P-F bonds o f PF5 to form (CF3)3PF2 in high yield. Due to the fast conversion of P-Cl bonds into P-F bonds by cadmium fluoride, PC15 forms (CF3)3PF2 as well, and a direct synthesis of (CF3)3PF2 with ca. 70 % yield starting from CdEt2, CF3I and PC15 is reported. Whereas no insertion o f CF2 into the axial bonds o f (CF3)3PF2 has been detected, reaction o f (CF3)2Cd with (CF3)3PC12 gives the new tetra-kis(haloalkyl)fluorophosphoranes (CF3)3(CF2C1)PF, (CF3)3(CFC12)PF, (CF3) 2 (CF2C1)2PF and (CF3)3(CC13)PF. The NMR spectra of these and related compounds and of their hydrolysis products (CF3)3(CF3_"Cln)PO are reported. The formation of the higher chlorinated phos phoranes is discussed in terms o f an isomerization mechanism presumably involving carbene elimination-reinsertion processes.

	Title	Carbene Adducts of Dimethylcadmium
	Abstract	The first examples of carbene-cadmium complexes are reported from the reactions of a variety of imidazol-2-ylidenes or imidazolin-2-ylidenes with dimethylcadmium. Four new carbene complexes are characterized by NMR spectroscopy ('H , i?C and 1 n Cd). The cadmium centers are strongly shifted downfield (100 -1 5 0 ppm) by interaction with the carbenes. X-ray structures are reported for three carbene-cadmium 1:1 adducts. The cadmium centers exhibit distorted trigonal-planar geometries in which the carbene ligands have an average 18.2 pm longer bond distance to cadmium compared to the methyl groups. The planes of cadmium coordination are twisted with respect to the plane of the imidazole ring. The more basic imidazolin-2-ylidene is shown to displace imidazol-2-ylidenes from the cadmium center.

	Title	Synthesis and Structure of RE2Rh2Cd (RE = La, Ce, Pr, Nd, Sm)
	Abstract	New intermetallic cadmium compounds /?£2Rh2Cd (r e = La, Ce, Pr, Nd, Sm) were syn thesized from the elements in sealed tantalum tubes in a high-frequency furnace. They were characterized through X-ray powder data: Mo2FeB2 type, space group P4/mbm, Z = 2. Single crystal data of the cerium compound (a = 762.8(1), c = 377.8(1) pm, wR2 = 0.0662, 199 F2 values, and 13 variable parameters) revealed small defects on the rhodium position leading to the composition Ce2R h186(3)Cd for the investi gated crystal. According to the course of the cell volumes Ce2Rh2Cd may be classified as a mixed-valent compound. The Ce2Rh2Cd structure is an intergrowth of slightly distorted A1B2 and CsCl related slabs of compositions CeRh2 and CeCd. Within the CeRh2 slab short Ce-Rh contacts (284-300 pm) are indicative of strong Ce-Rh bonding. The Rh-Rh distance within the A1B2 re lated slab is 289 pm.

	Title	Cadmium-Isocitrate Complex: Its Stability as a Function of Ionic Strength
	Abstract	The complexation of cadmium by isocitrate has been studied at 25 °C and pH 7.5 in a range of ionic strength from 0.01 to 0 j16. The formation constant of the complex between cadmium and tribasic isocitrate varies from 860 M -1 at ^ = 0 .1 6 to approximately 24,500 M -1 at infinite dilu tion. These data allow the distribution of the chemical forms of cadmium added to the incubation mixtures for the assay of NAD-dependent isocitrate dehydrogenase to be calculated.

	Abstract	In a series of 190 samples, higher fungi, especially from the genus Agaricus, were analyzed by atomic absorption spectroscopy on their content of the trace metals cadmium, zinc, and copper. Cd was found to be present in high concentrations in some Agaricus species belonging to special taxonomic groups. In relation to soil concentrations, Cd is highly enriched in some Agaricus spec., the enrichment being a taxonomic criterion of special value. Among the remaining genera of higher fungi, only Leucoagaricus and Amanita showed similiar enrichment properties for cadmium. The chemically related metals Zn and Cu were found to be relative uniformely distributed in all analyzed fungi. No synergistic or antagonistic relationship between Cd and the other two metals could be detected in the mushrooms.

	Title	Cadmium — ein Wachstumsfaktor für den Schiefknolligen Anischampignon Agaricus abruptibulbus (Peck) Kauffmann Cadmium as a Growth Factor for the Mushroom Agaricus abruptibulbus (Peck) Kauffmann
	Abstract	of Agaricus abruptibulbus, a mushroom which is known to accumulate cadmium, has been isolated and cultivated under definite conditions on agar plates or in a liquid medium in the absence and in presence of cadmium acetate. In.presence of 0.5-1.0 mg/1 Cd, mycelial growth of A. abruptibulbus is enhanced to 80% compared to the Cd-free controls, while above 4 mg Cd/1, the metal began to be inhibitory. The growth promoting effect of Cd was found to be independent from the supply of the organism with zinc. During growth in presence of Cd, an efficient uptake of the metal into the mycelium took place, a maximal 300 fold enrichment being observed with 10 mg Cd/1. Similar tests were performed with zinc, thereby showing a correlation between the uptake of both elements by the mushroom.
