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)的镍髤配合物[Ni(L1)(Mf)](1),1个含5-氯水杨醛缩水杨酰腙(H2L2)和吡啶(Py)的铜髤配合物[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髤与酰腙配体(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髤配合物,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髤原子具有五配位的NONO(O)四角锥配位构型。

关 键 词:Schiff碱  镍髤配合物  铜髤配合物  晶体结构

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.
Keywords:Schiff base  Nickel(Ⅱ) complex  Copper(Ⅱ) complex  crystal structure
