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。
Two multi-nuclear transition metal complexes containing tridentate Schiff base ligands and monodentate N-heterocyclic molecules were synthesized: one containing 5-chlorosalicylaldehyde reduced p-nitrobenzoylhydrazone (H2L1) and morpholine (Ni (L1) (Mf)] (1), a copper complex compound [Cu2 (L2) 2) containing 5-chlorosalicylaldehyde salicylhydrazone (H2L2) and pyridine (Py) 2] (2), and characterized by elemental analysis, infrared spectroscopy, ultraviolet spectroscopy and single crystal diffraction. In complex 1, the center Ni 配 coordinates with the phenolic oxygen, imine nitrogen, deprotonated oxygen atom and neutral morpholine nitrogen atom of acyl hydrazone ligand (L12-) to form a planar tetragonal N2O2 coordination structure , The adjacent complexes through the intermolecular hydrogen bonding into one-dimensional supramolecular chain structure. Complex 2 contains two crystallographically independent binuclear copper 髤 complexes. The phenolic oxygen atoms of adjacent complexes bridge two basic units of [Cu (L2) (Py)], respectively, forming two basic units containing Cu2 ( μ-O) 2 core complexes. Each Cu 髤 atom has a five-coordinated NONO (O) pyramid conformational configuration.
