摘　　要：合成了标题化合物。该化合物的分子式[Ni(C5H5N)2(C7H6O2N)2]H2O(C24H24N4NiO3),分子量475.18,采用单色的MoKα (λ = 0.71073 )射线测定,共收集7408个数据,其中独立衍射点2567个(Rint = 0.0272),I > 2s(I)可观测点数1926个,结果表明该化合物属单斜晶系, 空间群C2/c其晶胞参数为: a = 14.466(2),b = 12.193(2),c = 14.072(2) ;β = 116.229(2)°,V = 2226.6(5) 3,Z = 4,Dc = 1.418 g/cm3 ,μ = 0.905 mm-1,F(000) = 992. 2个水杨醛亚胺各提供2个配位原子参与配位,2个吡啶各提供1个配位原子参与配位,该配合物是六配位的八面体构型,同时讨论了该体系中不同配位原子的配位能力的差异。The complex [Ni(C5H5N)2(C7H6O2N)2]H2O was synthesized by the reaction of taurine salicylic Schiff base(TSSB), pyridine and nickel acetate in water-ethanol solution, and determined by X-ray diffraction method; but it was showed that the compound does not contain taurine. It belongs to monoclinic system, space group C2/c with a = 14.466(2), b = 12.193(2), c = 14.072(2) , β = 116.229(2), Mr = 475.18, V = 2226.6(5) 3, Z = 4, Dc = 1.418 g/cm3, μ = 0.905 mm-1 and F(000) = 992. The complex is two-dimensional formed through hydrogen bonding. The Ni(Ⅱ), coordinated by two oxygen atoms from two salicylic imine molecules and four nitrogen atoms from two pyridines and two salicylic imine molecules, forms an octahedral geometry. The abilities of various atoms coordinating to Ni(Ⅱ) are also discussed .
