| Synthese und Kristallstruktur von KCuHo2Mo40 16 Synthesis and Crystal Structure of K C uH o2M o40 I6  | | | | Abstract
| Single crystals o f K C uH o2M o40 16 have been prepared by recrystallisation from melts and investigated by X-ray diffractometer techniques. The compound crystallizes with m onoclinic symmetry, space group C 2/c, a = 521.6(1), b = 1251.3(2), c = 1953.1(2) pm, ß = 92.903(18)°, Z -4. K C uH o2M o40 16 represents a new structure type characterized by H oO s and alternate CuO6/K O 10 polyhedra chains. The connection o f these polyhedra chains to each other and by M o 0 4 tetrahedra is described and the crystal structure discussed with respect to related com pounds o f the C uLnM o2Os and K L nM o20 8 types. | | | |

| Uber das Erdalkalimetall-Lanthanoid | | | | Abstract
| Kupfer-Oxomolybdat (Cu0,22Mg0 ,78)BaNd2Mo4O 16 The Alkaline Earth R are E arth Copper-Oxomolybdate (C u 0 . 2 2 M g 0 . 7 8) B a N d 2 M o 4 O 1 6 Single crystals of (Cu0.22Mg0 78)B aN d2M o4O i6 have been prepared by crystallization from melts and investigated by X-ray methods. The compound crystallizes monoclinically, space group C ^ -C 1 2 /cl, Z = 4, a = 5.351(1), b = 12.891(2), c = 19.391(4) Ä, ß = 90.899(14)° and is isotypic to CuKHo2M o40 16. The crystal structure is dominated by B aO 10 and N d 0 8 poly-hedra forming a three-dimensional polyhedra network, which is filled by axially distorted (C u,M g)O fi octahedra and M o 0 4 tetrahedra. | | | |
