 Title    Zur Kenntnis von SrCo2V 208 und SrCo2(A s0 4)2 On SrCo2V20 8 and SrCo2(A s 0 4)2  
 Abstract    SrCo2V20 8 (I) and SrCo2(A s 0 4)2 (II) were prepared by crystallization from melts and investigated by X-ray single crystal technique. (I) is isotypic to the SrNi2V 20 8-type and crys­ tallizes with tetragonal symmetry, space group Cly-14-icd, a = 12.267; c = 8 .4 2 4 Ä ; Z = 8.

 Title    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.
