Abstract

Brown hexagons of the mixed valence V(V)/V(IV) arsenate (NH4)3[(VO)(V2O3)(AsO4)2(HAsO4)] were isolated in low yield from the reaction of VCl4, AS2O5, NH4Cl, H2O and (CH3)2NH in the mole ratio 1:2.5:6:169:8 at 150 °C for 144 h. The structure consists of an octahedral-tetrahedral framework, exhibiting both infinite {VO···VO···} chains and isolated binuclear units with the {V2O3} core. Crystal data: orthorhombic space group Pnma with a=7.204(3), b=13.741(4), c=14.831(3) Å, V=1468(2) Å3, Z=4, Dcalc=3.020 g cm-3, μ(Mo Kα) =82.57 cm-1; structure solution and refinement converged at an R value of 0.079.
