Two Cu(Ⅱ) and Ni(Ⅱ) complexes,[Cu(L1)2]· (1,4-dioxane) (1) (HL1=8-(((4-(1-((benzyloxy)imino)ethyl)phenyl)imino)methyl)-7-hydroxy-4-methyl-2H-chromen-2-one) and [Ni (L2)2] (2) (HL2=1-(4-(((2-hydroxynaphthalen-1-yl)methylene)amino)phenyl)ethanone O-benzyloxime),have been synthesized and characterized by elemental analyses,IR spectra,UV-Vis spectra,fluorescence spectra and X-ray single crystal diffraction method.X-ray crystallographic analysis shows that the Cu(Ⅱ) and Ni(Ⅱ) ions are all four-coordinated in a trans-N2O2 slightly distorted square-planar geometry by two hydroxy O and two imine N atoms from two N,O-bidentate Schiff base ligands.Moreover,complex 1 links some other molecules into an infinite 3D supramolecular structure by intermolecular hydrogen bonds and π… π stacking interactions,while complex 2 forms 1D infinite chain via intermolecular π… π stacking interactions.Furthermore,the fluorescence property of HL1,HL2 and their metal complexes 1 and 2 are discussed.CCDC:15429O1,1;1857932,2.%合成了2个含肟基Schiff碱的Cu(Ⅱ)和Ni(Ⅱ)配合物[Cu(L1)2]·(1,4-dioxane) (1)和[Ni(L2)2](2),并通过元素分析、红外光谱、紫外可见光谱,荧光光谱及X射线单晶衍射分析进行了表征和分析.结果表明,配合物1和2均包含1个中心金属离子和2个双齿配体单元,且金属离子的配位数均为4,均具有轻微扭曲的平面四边形几何构型.不同的是配合物1通过分子间氢键以及π…π堆积作用相连接形成了三维超分子结构,而配合物2仅通过分子间的π…π堆积作用形成了一条一维超分子链.
