 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.

Single crystals were investigated by X-ray diffrac­ tion and showed triclinic symmetry, space group C j-P l. The structures are isotypic to C o9(B 20 5) with the lattice parameters (A) « = 331.28(6), 6 = 613.87(11), c = 922.2(2), a = 104.067(11) °, ß = 90.672(13) °, y = 92.413(12) 0 and (B) 0 = 315.89(2), 6 = 612.84(6), c = 927.72(6), a = 104.103(7) °, ß = 91.020(6) °, y = 92.540(7) °, Z = 2. All metal point positions show an octahedral oxygen coordination and a partly statistical distribution o f Zn2+ and N i2+ or C o2+, respectively. Isolated nearly planar B20 5 units connect ribbons consisting o f edge sharing metal octahedra.

 Title    Cox 5Ti0 5(B 0 3) 0 and Co! 5Zro.5(B 0 3) 0  
 Abstract    Single crystals of Co15Tio.5(B 0 3)0 (I) and Coj 5Zr0 5(BO3)O (I I) were obtained by a B20 3 flux technique. Both compounds crystallize with orthorhombic symmetry, space group D -Pnma (Nr. 62), I a = 928.1; b = 311.1; c = 940.1 pm; Z = 4 and I I a = 949.5; b = 323.42; c = 934.7 pm; Z = 4. The compounds are isotypic to the mineral warwickite. All metal ions are octahedrally coordinated by oxygen ions. The structure contains isolated, trigonal planar B 0 3 units and oxygen that is not coordinated to boron.
