 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    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.

They form dark red crystals, which were characterized by their IR specta as well as by X-ray crystal structure determinations. All complexes [Na-15-crown-5] 2 [M(Se 4) 2 ] with M = Zn (1), Cd (2), Hg (3) crystallize isotypically in the space group C2/c with 4 formula units per unit cell. In the anions [M(Se 4) 2 ] 2 ^ the metal atoms are coordinated tetrahedrally by four selenium atoms of two Se 4 2 ~ units, thus forming a spiro-bicyclus. The complex cations [Na-15-crown-5] + have a Na---Se contact of approximately 299 pm with two selenium atoms of a MSe 4 group, allowing formulation of triple ion species.
