Abstract

The hydrothermal reaction of V2O5, BaCl2 ·2H2O, ethylenediamine and H2O in the mole ratio 1:1:2.8:925 at 200°C for 5 days yielded black crystals of Ba5.33(H3O)0.33[V10O30] in 20% yield. The structure consists of discrete decavanadate clusters [V10O33] 11- and Ba2+ and H3O+ cations. The molecular anion is constructed from four {V2O7)4- units, each acting in a bidentate linkage mode to the central (V2O2}5+ unit. The tetrahedral sites associated with the {V2O7}4- moieties are in the +5 oxidation state, while the reduced site is delocalized over the two central square pyramidal sites. Crystal data for HBa5.33O30.33V10: cubic Im3̄, a= 16.9439(2) Å, V=4864.5(1) Å3 Z=6, Dcalc = 3.540 g cm-3; R=0.0255 for all 1077 reflections.
