The title complex[Ni(C10H8N2)(C7H4O5N3)(H2O)]ClO4 was synthesized by Taurine 2-hydroxy-3,5-dinitrobenzaldehyde schiff base,2,2’-bipyridine and nickel(II) perchloride in ethanol solution,and the crystal structure was determined by X-ray diffraction method.The crystal belongs to Monoclinic system,space group P21/c,with cell parameters:a=7.4481(3),b=24.1832(9),c=11.6691(4),β=98.021(2)°,V=2081.26(13)3.The nickel(II) atom is coordinated by two N atoms from one 2,2’-bipyridine molecule,one O atom and one N atom from a 2-hydroxy-3,5-dinitrobenzaldehyde imine molecule,one O atom from a coordinated water,resulting in a square-pyramid geometry.The packing diagram shows that a three-dimensional network is formed via intermolecular attractive force.
