| Ein Beitrag zur Kristallchemie von Verbindungen mit Johillerit-Struktur: On the Crystal Chemistry of Compounds with Johillerite Structure: KCo3 Cu(As2 5 8 V0 4 2 )O i2  | | | Abstract
| Single crystals of KCo3Cu(As2.58Vo42) 0 12 were prepared by solid state reactions below the melting point of the reaction mixture (K 2C 0 3, CuO, CoC20 4, V 20 5 and 3 A s20 5 -5 H 20) . It crystallizes with m onoclinic symmetry, space group C |h-C 2 lc, a = 12.207, b = 12.730, c = 6.811 A , ß = 113.69°, Z -4. The structure type is characterized by isolated twisted-square C u 0 4-polygons, C o 0 6-octahedra and a special 4+4-coordination o f the potassium ion. A s5+ and V*+ are in tetrahedral coordination with a partly statistical distribution of these ions. | | |

| 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. | | |
