摘要：

Single crystals of KCo3Cu(As2.58V0.42)O-12 were prepared by solid state reactions below the melting point of the reaction mixture (K2CO3, CuO, CoC2O4, V2O5 and 3 As2O5.5H(2)O). It crystallizes with monoclinic symmetry, space group C-2h(6)-C2/c, a = 12.207, b = 12.730, c = 6.811 Angstrom, beta = 113.69 degrees, Z = 4. The structure type is characterized by isolated twisted-square CuO4-polygons, CoO6-octahedra and a special 4-4 coordination of the potassium ion. As5+ and V5+ are in tetrahedral coordination with a partly statistical distribution of these ions.
