| 摘要: 制备了一种水杨醛类多齿Schiff碱（H3Lds,1），并合成了2种金属配合物[CuCl（H2Lds）]·H2O（2）和[Co2（H2O）2（Lds）2]·5H2O（3）。X射线单晶衍射分析结果表明，1属正交晶系P212121空间群，分子间氢键将该化合物H3Lds连接成二维超分子网络。2属正交晶系Pbca空间群，它是一种具有平面四边形构型的单核铜配合物。而3属单斜晶系P21/c空间群，它是一种双核钴配合物，其中Co（Ⅲ）处于畸变的八面体配位环境。2和3借助分子间氢键均形成了一维超分子链。 |

| Abstract: A multidentate Schiff base ligand (H3Lds,1) with[NO3] donor set, derived from the condensation of salicylaldehyde and 2-Amino-2-methyl-1,3-propanediol, reacted with copper(Ⅱ) chloride or cobalt(Ⅱ) acetate to yield two complexes[CuCl(H2Lds)]·H2O(2) and[Co2(H2O)2(Lds)2]·5H2O(3). The ligand and complexes were characterized by elemental analysis, IR, UV spectra and X-ray diffraction analysis. The results reveal that 1 crystallizes in orthorhombic space group P212121, 2 with Cu(Ⅱ) in distorted square-planar coordination in orthorhombic space group Pbca, 3 with Co(Ⅲ) in distorted coordination octahedron in monoclinic space group P21/c, respectively. The H3Lds is linked by intermolecular H-bonds to form two-dimension supramolecular network, while both complexes are connected by intermolecular hydrogen-bonding interactions to form a supramolecular chains, respectively. |
