摘　　要：合成所得双(N-氧化吡啶-2-甲醛)缩1,2-丙二胺的镍(Ⅱ)配合物[Ni(piopn)(H_2O)_2](ClO_4)_2的晶体属空间群C_?~4-C_c,晶胞参数α=7.397(3)A,b=13.187(7)A,c=25.502(14)A,β=102.18(4)°. 用分子轨道理论的近似方法分析了该配合物的电子结构和分子轨道,探讨了分子的结构特征与红外光谱的关系。A new nickel(Ⅱ) complex with bis-schiff bases from picolinaldehyde N-oxideand 1, 2-propanediamine, [Ni (piopn) (H_2O)_2] (ClO_4)_2 has been synthesised and its cry-stal structure has been determined. The crystal belongs to monoclinic system, spacegroup C_o, with cell dimensions: a = 7.397 (3) A, b = 13.187 (7) A, c = 25. 502 (14) A,β = 102.18(4)°, V = 2241.0 A, D_o= 1.71g·cm^(-3), F(000) = 1135.8, μ = 11.65cm^(-1).According to the semiempirical MO theory calculation, the relationships between IRfrequency shifts of υ_(C-N) and υ_(N-O) bands and their characteristics of chemical bondshave been discussed.
