Abstract

The reaction of (NH4)6Mo7O24·2H2O and NH4VO3 with 3-aminbenzonitrile in aqueous solution (pH = 2) at room temperature furnishes a new β-octamolybdate [(C7H7N2)3(NH4)]2[Mo8O26]2·4H2O (1). The title compound crystallizes in triclinic system, space group P-1, a = 12.0940(4) Å, b = 13.9373(6) Å, c = 15.0625(3) Å, α = 80.479(8)°, β = 83.013(2)°, γ = 66.694(5)°, V = 2295.2(2) Å3, Z = 1, λ(Mo Kα) = 0.71073 Å. The refinement of the structure leads to a residual factor R = 0.0560 for 5010 reflections [I > 3σ(I)]. The structure of 1 consist of β-[Mo8O26]4− with (C7H7N2)+ and (NH4)+cations connected to the mineral parts by hydrogen bonds.
