| (V0)4(As0 4)2(As20 7): Ein neues Divanadyl(IV)-Arsenat mit flächenverknüpften V20 8+1-Oktaederdoppeln Ba(V0)4(As0 4)2(As20 7): A New Divanadyl(IV)-Arsenate Containing Face Shared V20 8+, Double A new alkaline earth vanadyl arsenate Ba(V0)4(As0 4)2(As2 0 7) has been synthesized by solid state reactions in closed quartz tubes. X-ray investigations led to orthorhombic symmetry, space group D2£-Pnma, a = 17.540(2), b = 7.6223(8), c = 11.0633(12) A, Z = 4. The crystal structure is characterized by A s 0 4 single and As20 7 double tetrahedra and face shared asymmetric stretched V20 8+, double octahedra, forming a network of polyhedra. The incorporated Ba2+ ions show 12-fold coordination by oxygen. Ba(V 0)4(A s0 4)2(As20 7) is the first vanadyl compound containing V20 8 divanadyl groups originating from face sharing stretched V 0 5+l octahedra. | | | |
