英文摘要	合成了两种配合物晶体［Ｎｉ（ｉｍ）６］（ＮＯ３）（ＯＨ）（Ｈ２Ｏ）４（Ⅰ）和［Ｎｉ（ｉｍ）４（Ｈ２Ｏ）２］［Ｃ６Ｈ４（ＣＯＯ）２］（Ⅱ）（ｉｍ＝Ｃ３Ｈ４Ｎ２）．晶体结构测定表明，晶体（Ⅰ）属于六方晶系，空间群Ｐ６３／ｍ，ａ＝０．８９８５（１０）ｎｍ，ｃ＝２．１００２（４）ｎｍ，Ｖ＝１．４６８５（４）ｎｍ３，Ｚ＝２，Ｒ＝０．０４３，Ｒｗ＝０．０４５．晶体（Ⅱ）属单斜晶系，空间群Ｃ２／ｃ，ａ＝２．２２０７（４）ｎｍ，ｂ＝０．７６６５（２）ｎｍ，ｃ＝１．６０４３（３）ｎｍ， β＝１２０．６０（３）°，Ｖ...; The crystals of two complexes [Ni(im)(5)](NO3)(OH) (H2O), (I) and [Ni(im)(4) (H2O)(2)][C5H4(COO)(2)] (I) were synthesized. The structures of single crystals were determined by X-ray diffraction, The crystal ( I) is of hexagonal system, space group P6(3)/m with a = 0. 838 5(10) nm, c = 2. 100 2(4) nm, V= 1. 468 5(4) nm(3), Z = 2, R = 0. 043, R-w = 0. 045, The crystal (I) is monoclinic system, space group C2/c with a = 2. 220 7(4) nm, b= 0. 766 5(2) nm, c = 1. 604 3(3) nm, beta = 120. 60(3)degrees, V = 2. 350 3(9) nm(3), Z = 4, R = 0. 056, R-w = 0. 079. The prominent feature of these two complexes is that they have various hydrogen bondings and thereby possess infinite three-dimensional networks. This not only increases the crystal structure stability but also forms hydrogen bonded charged-transfer system, which modulates and promotes the electron transfer between the molecules. The temperature dependence of the magnetic susceptibility was measured and discussed.; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 7; 11; 1671-1676; 20
