A new polyoxomolybdate compound [Zn(HL)2(Mo8O26)(4,4-Bipy)]·(4,4-Bipy)(HL = 3-(2-pyridyl)pyrazole, 4,4-Bipy = 4,4-bipyridine) 1 has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction, elemental analyses, TG and IR spectroscopy. The compound crystallizes in monoclinic, space group C2/c with a = 18.060(4), b =13.870(3), c = 19.360(4) (A), β - 93.50(3)°, V- 4840.5(17) (A)3, C36H30Mo8N10O26Zn, Mr= 1851.59,Dc = 2.541 g/cm3, μ(MoKα) = 2.589 mm-1, F(000) = 3560, Z = 4, the final R = 0.0328 and wR =0.0870 for 4005 observed reflections (I > 2σ(I)). X-ray diffraction analyses reveal that compound 1 is constructed from Mo8O264- units linked by Zn(HL)22+ and 4,4-Bipy. Mo8O264- is connected by Zn(HL)22+ via terminal oxygen atoms along the [010] axis forming chains, which are further linked by 4,4 -Bipy. along the [001] axis forming a two-dimensional network structure.
