一系列不同结构的配位配合物[Hg(iimb)I2]·0.5丙酮(1)、[Hg(bib)Br2]·0.5THF(2)、[Hg(bib)I2](3)、[Hg3(tib)2I6]·2DMF(4)、[Hg3(timpt)2I6]·4H2O(5)、[Hg2(titmb)Br4] (6)和[Hg2(titmb)Cl4](7)是通过卤化汞(II)与相应的含咪唑二齿或三足配体反应合成的，即1-(1-咪唑基)-4-(咪唑-1-基甲基)苯(iimb)、1-溴-3,5-双(咪唑-1-基甲基)苯(bib)，分别为1,3,5-三(1-咪唑基)苯(tib)、2,4,6-三[4-(咪唑-1-基甲基)苯基]-1,3,5-三嗪(timpt)和1,3,5-三(咪唑-1-基甲基)-2,4,6-三甲基苯(titmb)。通过单晶X射线衍射分析确定了配合物的结构，结果表明1、2和4−7是具有不同形状的一维（1D）链配位聚合物。在3的情况下，两个金属原子和两个bib配体形成M2L2双核环，它们通过弱Hg…I相互作用进一步连接，形成i...
A series of coordination complexes with different structures [Hg(iimb)I2]·0.5acetone (1), [Hg(bib)Br2]·0.5THF (2), [Hg(bib)I2] (3), [Hg3(tib)2I6]·2DMF (4), [Hg3(timpt)2I6]·4H2O (5), [Hg2(titmb)Br4] (6), and [Hg2(titmb)Cl4] (7) were synthesized by reactions of mercury(II) halides with the corresponding imidazole-containing bidentate or tripodal ligands, namely, 1-(1-imidazolyl)-4-(imidazol-1-ylmethyl)benzene (iimb), 1-bromo-3,5-bis(imidazol-1-ylmethyl)benzene (bib), 1,3,5-tris(1-imidazolyl)benzene (tib), 2,4,6-tris[4-(imidazol-1-ylmethyl)phenyl]-1,3,5-triazine (timpt), and 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (titmb), respectively. The structures of the complexes were determined by single-crystal X-ray diffraction analyses, and the results revealed that 1, 2, and 4−7 are one-dimensional (1D) chain coordination polymers with different shapes. In the case of 3, two metal atoms and two bib ligands form M2L2 binuclear rings, which are further connected by weak Hg···I interactions to form an i...
