 Title    Two Examples of Partial and Total Defects in the B a«Ln2Mo4O i6-Type: BaCu0 41 ■o,59Pr2Mo4 0 16 and BaBYb2Mo4Ojg  
 Abstract    Single crystals of (I) BaCu0.4iPr2M o4O 16 and (II) BaYb2M o40 16 have been prepared by flux technique. Both compounds crystallize with m onoclinic symmetry, space group C2h-C 2 /c with (I): a = 5.352(11), b = 12.888(2), c = 19.399(4) A; ß = 90.89(3)°; (II): a = 5.181(7), b = 12.467(3), c -19.350(3) Ä , ß -91.93(2)°, Z = 4. The crystal structure is characterized by i [ B a M 0 12]-chains along [010]. In the first case the M positions are occupied by copper by about 41%, in the second case these positions remain com pletely unoccupied. With respect to the crystal chemistry of the reference compound Ba(Cu0.22Mg() 78)Nd2Mo4O 16 all substan­ ces of the composition BaLn2M o40 16 should be written as Ba»Ln2Mo40 16 indicating the holes in th e^ B a M O i^ -c h a in s by ■.

M üller-B uschbaum * PbCu3T e07 has been prepared from the element oxides by solid state reaction in air. Single crystal X-ray work led too orthorhombic symmetry, space group D^-Pnma, a = 10.488(1), b = 6.353(2), c = 8.813(2) A, Z = 4. Cu(1)0 5 square pyramids and Te06 octahedra are members of the anionic part of the crystal structure, Cu(2) atoms show tetrahedral coordination by oxygen. The C u (2)2+ and the Pb2+ cations are incorporated into a [Cu(l)2Te07] network. PbCu,Te07 can thus be viewed as a lead copper oxocuprate(II) tellurate. Calculations of the Coulomb terms of lattice energy reveal two possible positions for the lone pair of electrons at Pb'+.

 Abstract    Nearly colourless single crystals of the compounds CuDy2 [B80 i 6] (I) and CuHo2[B80)6] (II) have been obtained by a B20 3 flux technique. They crystallize in the structure of CuTb2 [B80)6] (I) or in an orthorhombic variant (II). X-ray investigations on single crystals led to the space group C2h -P2!/c (Nr. 14) with lattice parameters a = 1025,5(10); b = 836,99(10); c = 621,2(8) pm, ß = 90.47(10)°; Z = 2 (I) and D^h -Pbam (Nr. 55) with a = 840,7(2), b = 616,6(2), c = 1022,0(2) pm, Z = 2 (II). The structures contain 1 [B80 16]8_ chains isolated from each other, which include tri-and tetracoordinated boron, T'fie chains consist of alternating twelve and eight-membered rings of boron and oxygen atoms connected by B 0 4 units. Dy,+ and H o 3+ are octacoordinated and Cu2+ is hexacoordinated in elongated octahedra by oxygen. The relation between these two structures is discussed.

 Title    CuHo2[B20 5]2* Ein unerwarteter Strukturtyp in der Reihe der Kupferlanthanoidborate CuHo2[B20 5]2: An Unexpected Structure Type in the Series of Copper  
 Abstract    Single crystals of the new compound CuHo2 [B20 5 ]2 were obtained by using a B20 3 flux technique with CuO and Ho20 3 at 1050 °C. X-ray investigations on single crystals led to the space group P 2,/c (Nr. 14) with lattice parameters a = 454.3(2); b = 726.0(4); c = 936.0(5) pm; ß = 90.77(1)°; Z = 2. The compound is isotypic to CuTb2[B20 5 ] 2 as well as to the gadolinite structure (FeY2 [BeSi05]2). The structure exhibits layer-like 2 [B20 5]4~, a two-dimensional anion consisting of edge sharing B 0 4 -tetrahedra, which form four-and eight-membered rings. The layers are connected by elongated C u06-octahedra and slightly distorted tetragonal LnOs-antiprisms.

 Title    B aC u 6G e2S8 -Ein Thiogermanat als Variante der L i3Bi-Struktur BaCu6Ge2S8 -A Thiogermanate as a Variant of the Li3Bi Structure  
 Abstract    BaCu6Ge2S8 was synthesized by direct reaction of the elements at 750°C and characteri­ zed by X-ray single crystal techniques. The thiogermanate crystallizes in a new orthorhombic structure type (a = 6.122(1) A, b = 12.084(3) A , c = 17.614(5) A; Pbcm, Z = 4). Isola­ ted [GeS4]4_ tetrahedra form a slightly distorted cubic face-centered (fee) arrangement. Ba-and Cu-atoms each occupy half the octahedral gaps (O G) of this " tetrahedra packing" . Fur­ ther Cu atoms fill the tetrahedral gaps (T G) completely. The compound can be written as Ba2<l/2 0 G,(Cu2)2<l/2<:)G)Cu8<7G)(GeS4)4 . Thus the structure o f BaCu6Ge2S8 can be derived from the Li^Bi type. The sulfur coordination o f the metal atoms (Cu tetrahedral or trigonal, Ba with CN 8) are realized by the spatial orientation of the [GeS4]4~ tetrahedra. Their centers nearly maintain the fcc-arrangement. This structure interpretation of BaCu6 Ge2S8 from the viewpoint o f a " filled tetrahedra packing" is discussed for further known thiogermanate compounds.

 Title    Schwermetalle in höheren Pilzen Cadmium, Zink und Kupfer Heavy Metals in Higher Fungi Cadmium, Zinc, and Copper  
 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    Binuclear Copper Electron Paramagnetic Resonance Signals of a-Methemocyanin of Helix pomatia  
 Abstract    The binuclear electron paramagnetic resonance signals o f a-methemocyanin o f Helix pomatia were investigated at liquid helium temperatures. These signals were completely eliminated by the addition of fluoride and enhanced in the presence o f chloride, which did not alter the saturation behavior. The triplet nature of the signal at g = 4.59 was confirmed by the low power-saturation. The addition of nitrite at pH 5.0 and 0° C yielded slowly and reversibly a seven-line half-field signal. On lowering the temperature the intensity of the triplet signals increased to the lowest tem­ perature reached 4.2 K, excluding a strong exchange coupling.

 Title    The Kinetics of the Reaction of Thiocyanate and Nitrite Ions with Orconectes limosus Oxyhemocyanin  
 Abstract    The time course of the reaction of oxyhemocyanin from the arthropod Orconectes limosus with SCN" and N 0 2 " was investigated. After addition of one of these anions to oxyhemocyanin solu­ tion an exponential decay of A 340 was found, indicating a removal of oxygen from the active site. The order of reaction with respect to ligand was about 3 for thiocyanate and about 1 for nitrite. On this basis, a possible arrangement of ligands in the active site has been proposed. The final product of reaction with SCN" yielded a mononuclear copper EPR spectrum while the reaction product with N 07 gave a characteristic spectrum of two coupled Cu2+ ions. It was possible to remove the ligands from the active site by dialysis. The reaction patterns showed distinct changes in a narrow pH range, 5.3—6.5. A possible effect of structural alterations of the protein moiety on the course of the reaction of oxyhemocyanin with ligands is suggested.

 Title    Effects of Heavy Metals on the Fast Chlorophyll Fluorescence Induction Kinetics of Photosystem II: a Comparative Study  
 Abstract    The effects of toxic concentrations of Cu, Zn and Cd on the fast induction kinetics of fluorescence from photosystem(PS)II were investigated in a comparative way. The fast fluo­ rescence transient from primary leaves of m etal-treated bean plants was studied. During several days after metal application, the time course of the changes induced by the different metals was monitored. The results evidenced not only a different time course of the changes in fluorescence related parameters for the three metals, but also different effects on the fluorescence induction kinetics, which could possibly be linked to different mechanisms of action of the metals.
