| 摘要: 合成了2个含三齿Schiff碱配体和单齿N-杂环分子的多核过渡金属配合物：1个含5-氯水杨醛缩对硝基苯甲酰腙(H2L1)和吗啡啉(Mf)的镍(Ⅱ)配合物[Ni(L1)(Mf)] (1)，1个含5-氯水杨醛缩水杨酰腙(H2L2)和吡啶(Py)的铜(Ⅱ)配合物[Cu2(L2)2(Py)2] (2)，并通过元素分析、红外光谱、紫外光谱以及单晶衍射等手段进行表征。在配合物1中，中心Ni(Ⅱ)与酰腙配体(L12-)的酚氧、亚胺氮、去质子酰胺氧原子以及中性吗啡啉氮原子配位形成平面四方形的N2O2配位构型，相邻配合物通过分子间氢键作用构筑成一维超分子链状结构。配合物2中含有2个晶体学上独立的双核铜(Ⅱ)配合物，相邻配合物分子的酚氧原子分别桥联2个[Cu(L2)(Py)]基本单元，形成2个含有Cu2(μ-O)2核心的配合物。每个Cu(Ⅱ)原子具有五配位的NONO(O)四角锥配位构型。 |

| Abstract: Two polynuclear transition metal complexes with a monodentate heterocycle and tridentate Schiff base ligands have been synthesized and characterized by elemental analysis, IR, UV and X-Ray diffraction. One is nickel(Ⅱ) complex [Ni(L1)(Mf)] (1) with 5-chlorosalicylaldehyde 4-nitrobenzoylhydrazone (H2L1) and morpholine (Mf), the other is copper(Ⅱ) complex [Cu2(L2)2(Py)2] (2) with 5-chlorosalicylaldehyde salicyloylhydrazone (H2L2) and pyridine (Py). In compound 1, the Ni(Ⅱ) ion is coordinated by three donors (phenolate-O, imine-N and deprotonated amide-O atoms) from the ligand L12- and the N atom of the neutral morpholine, forming a square-planar N2O2 coordination geometry. In the crystal, every two molecules related by centrosymmetric operation in compound 1 are connected through intermolecular hydrogen bonds, forming one-dimensional chain. There are two crystallographically binuclear copper(Ⅱ) units in complex 2. The two metal centres are bridged by the phenolate O atoms of the neighboring ligand, forming two Cu2O2 quadrangle. Each Cu(Ⅱ) ion has a square-pyramidal geometry. CCDC: 846209, 1; 846210, 2. |
