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=0.898 5(10) nm , c= 2.100 2(4) nm , V= 1.468 5(4) nm 3, Z= 2, R= 0.043, Rw = 0.045. 晶体(Ⅱ)属单斜晶系, 空间群C2/c, a= 2.220 7(4) nm , b= 0.766 5(2) nm , c= 1.604 3(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 |
