A hydrothermal reaction of zinc acetate with molybdenum trioxide, vanadium pentoxide, phosphorus pentoxide and 2,2?-bpy (2,2?-bipyridine) led to the title compound [Zn(2,2?- bpy)2(H2O)]2[HPMo12O40(VO)2] 1. Single-crystal X-ray diffraction revealed that 1 (C40H36- N8O44PV2Zn2Mo12) crystallizes in the triclinic system, space group P1 with a = 11.881(2), b = 12.468(2), c = 12.622(2) ?, α = 71.333(8), β = 74.485(4), γ = 86.896(5)o, V = 1705.8(4) ?3, Mr = 2747.64, Z = 1, Dc = 2.675 g/cm3, μ = 3.201 mm-1, F(000) = 1309, S = 1.070, the final R = 0.0697 and wR = 0.1905 for 5368 observed reflections with I > 2σ(I). Compound 1 is built on a mixed-metal bicapped [HPMo12V2O42] subunit covalently bonded to two [Zn(2,2?-bpy)2(H2O)]2+ clusters via terminal oxygen atoms of the capping V atoms. Each Zn atom is six-coordinated by four nitrogen atoms from two 2,2?-bpy ligands, one terminal oxygen atom from coordinated water mole- cule and another one from the capped {VO} unit.
