摘要

A new polyoxomolybdate compound [Zn(HL)(2)(Mo8O26)(4,4'-Bipy)]center dot(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) angstrom, beta = 93.50(3)degrees, V = 4840.5(17) angstrom(3), C36H30Mo8N10O26Zn, M-r = 1851.59, D-c = 2.541 g/cm(3), mu(MoK alpha) = 2.589 mm(-1), F(000) = 3560, Z = 4, the final R = 0.0328 and wR = 0.0870 for 4005 observed reflections (I > 2 sigma(I)). X-ray diffraction analyses reveal that compound 1 is constructed from Mo8O264- units linked by Zn(HL)(2)(2+) and 4,4'-Bipy. Mo8O264- is connected by Zn(HL)(2)(2+) 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.
