摘要
A novel organic-inorganic hybrid polyoxovanadate, [Ni（bpp）2]2（V4O12） （bpp= 1,3-bi-4-pyridylpropane）, was hydrothermally synthesized from a mix.ture of NiCl2＊6H2O, NH4VO3, bpp, EtOH and H2O. The crystal structure consists of ∞^2[Ni（bpp）2]^2＋, two-dimensional networks interpenetrating perpendicularly with each other, and （V4O12）^4-, cyclic tetranuclear clusters linking the ∞^2[Ni（bpp）2]^2＋ networks to form a three-dimensional coordination framework. The crystal belongs to tetragonal space group I41/a with unit cell parameters, a= 2.14705 nm, c= 1.29293 nm. UV-Vis-NIR reflectance spectroscopy study revealed insulator nature for the crystal with an optical energy gap of 2.70 eV.
