| Geordnete Metallverteilung in K B a V 0 4 und K S rV 0 4 mit /?-K2S 0 4-Struktur Ordered Metal Distribution in K B a V 0 4 and K S r V 0 4 Showing p -K 2S 0 4 Structure  | | | | Abstract
| Single crystals of K B a V 0 4 (I) and K S rV 0 4 (I I) have been prepared by crystallization from V 20 5 flux. The yellowish crystals show orthorhombic symmetry, space group D'^-Pnma with (I): a = 7.774(2), b = 5.899(1), c = 10.375(2) A , (II): a = 7.400(2), b = 5.812(1), c -9.961(1), Z = 4. Both compounds show an ordered distribution o f K + and Ba2+ and Sr2+ respectively. The different sizes of the K 0 1() and BaOy (S r 0 9) polyhedra are discussed with respect to those of the /3-K2S 0 4 structure, considering the calculations o f the Coulomb terms of lattice energy. | | | |
