 Title    Synthesis and Crystal Structure of (Cu,Zn)3 7 5 Mo30 12  
 Abstract    Single crystals of (Cu,Zn)3 75Mo30 12 have been prepared by crystallization from melts and investigated by X-ray diffractometer techniques. (Cu,Zn)3 75Mo3Oi2 crystallizes orthorhom-bically, space group D^-P212,21, Z = 4, a = 17.947(9), b = 5.092(3), c = 10.685(5) A. It is isotypic to Cu385Mo30 12. All molybdenum atoms are tetrahedrally coordinated by oxygen atoms. There are layers of C u 0 6 and Z n 0 6 octahedra, while other metal sites are occupied by copper in a deformed prismatic coordination with one oxygen atom at a remarkably greater distance from copper than the other five. Some of the zinc atoms occupy positions in chains of face-sharing octahedra with an occupancy factor of 0.75. The crystal structure is discussed with respect to the isotypic compound Cu385Mo30 12 and compounds of the type CuLnMo20 8.

 Abstract    Single crystals of AgKCu3Mo40 16 have been prepared by crystallization from melts and investigated by X-ray diffractometer techniques. This compound crystallizes with monoclinic symmetry, space group C |h-P 2 Je, a = 5.056(1), b = 14.546(4), c = 19.858(9) Ä, ß = 86.64(5)°, Z = 4. The crystal structure of AgKCu3Mo40 16 is closely related to K2Cu3Mo40 16 showing ribbons of edge-sharing C u 0 6 and AgÖ7 polyhedra. The ribbons are linked by tetrahedrally coordinated molybdenum and K2O 10 groups. Another kind of M o 0 4 tetrahedra occupies the cavities inside the ribbons. The crystal structure and the coordination of silver, copper, potas­ sium and molybdenum by oxygen are discussed with respect to K2Cu3Mo40 16.

 Abstract    uT m 2[ B 20 5] 2: D as erste "M etaborat" mit einem x [ B 20 5] 4 -Anion CuTm2[B20 5]2: The First " Metaborate" with a ^ [ B ^ s ] 4 -Anion Single crystals o f the compound CuTm2[B 20 3]2 were obtained by a B20 3 flux technique. The compound contains a hitherto unknown metaborate anion with the formula ^ [ ^ O s ] 4-. It crystallizes in the monoclinic space group C|h-P2!/c with a = 452.18(7); b = 720.0(2); c = 929.2(5) pm; ß -90.16(5)°; Z = 2. The metaborate layers consists of four and eight membered rings of edge-sharing B 0 4-tetrahedra resembling the complex anion in the isotypic gadolinite structure of F e Y 2[B eS i0 3]2. The layers are connected via copper-centered elongated oxygen octahedra and slightly distorted thulium-centered tetragonal oxygen antiprisms.

 Title    On the Oxocuprate (C u,C o)375Mo30 12  
 Abstract    Single crystals of (C u,C o)3 7?Mo30 12 have been prepared by recrystallization from melts and investigated by X-ray diffractometer techniques. TTie compound crystallizes with ortho-rhombic symmetry, space group D'2 6 h-P n m a , a = 5.092(1), b = 10.624(3), c = 17.804(4) A, Z = 4 and is isotypic to NaCo2.3iMo30 12. The crystal structure is discussed and it is shown, that the trigonal prismatically coordinated copper positions are occupied in a different m an­ ner. One of the alternate sites is beside the centre of the prisms, and the other one is shifted towards one of the faces of the rectangular prism. This detail may be interpreted by assigning the valance states C u1 and Cu11. The M 0 6 octahedra are occupied statistically by copper and cobalt.

 Abstract    Single crystals of the new com pounds CuLn2[B20 5]2 (Ln = Er3+(I), Lu3+(II)) were ob­ tained by a B9O 3 flux-technique. They crystallize in the space group C ih -P 2 \lc with I: a = 453.14(6); b = 721.94(5); c = 929.5(4) pm; ß = 90.01(3)°; Z = 2 und II: a = 451.4(4); b = 718.3(1); c = 928.1(3) pm; ß = 90.00(6)°; Z = 2. The compounds are isotypic to CuTm2[B20 5 ] 2 as well as to the mineral Gadolinite (FeY 2 [B eSi0 5 ]2) and exhibit layer like 2.[B20 5]4 --anions consisting of edge sharing B 0 4 -tetrahedra, which form four-and eight-membered rings. The borate anions are separated by layers of elongated C u 0 6-octahedra and slightly distorted tetragonal L n 0 8-antiprisms.

 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    Kristallstrukturuntersuchung an einem bismuthaltigen Hollandit: Crystal Structure Investigation of the Bismuth Containing Hollandite: Bij 9Cu4V40 16  
 Abstract    Single crystals of B^ 9Cu4V 4O i6 have been prepared by quenching of CO2-LA SER heated samples. They were investigated by X-ray techniques. The compound^ crystallizes with tetra­ gonal symmetry, space group C4h-I 4 /w , a = 9.945(2) A, c = 2.915(3) A, Z = 1, and is isotypic to the mineral Hollandite. B^ 9Cu4V4O i6 is the first Hollandite with a statistical distribution of vanadium and copper in the network o f octahedra. Calculations of the Coulomb terms of lattice energy led to a distance o f bismuth to the lone pair of 1.07 A. Considering the lone pair as part of the coordination sphere of Bi3+ a square pyramidal polyhedron is obtained.

 Title    Silke  
 Abstract    The compound Cu2 Z n(B 2 0 s) 0 was prepared by using a B 2 0 3 flux technique, and single crystals were investigated by X-ray diffraction (monoclinic symmetry, space group C2 h-P 2 i/c). The structure is isotypic to Cu2 C o(B 2 0 5) 0 with lattice parameters a = 327.38(2), b = 1479.4(3), c = 915.39(13), ß = 95.794(11)°, Z = 4, but with the significant difference that zinc is penta-coordinated by oxygen. Copper exhibits a nearly square planar or a square pyramidal coordi­ nation, respectively. The structure contains isolated B2 0 ? units and oxygen which is not coordinated to boron.
