摘要
以2-甲基-5-(2-吡啶基)-1,3,4-噁二唑(L)为配体合成了[Cu2L2(μ-Cl)2Cl2](1)和[CdL2(NO3)2](2),测定了X射线单晶结构,用红外光谱、紫外光谱、荧光及热重分析进行了表征。配体L和配合物2属于单斜晶系,配合物1属于三斜晶系。L,1和2的空间群分别为P21/c,P1和C2/c。配合物1是通过2个氯原子(Cl1,Cl1i)桥联形成的双桥双核Cu(Ⅱ)配合物,具有畸变四方锥构型[CuCl3N2]。配合物2具有畸变八面体构型[CdN4O2]。
2-Methyl-5-(2-pyridyl)-1,3,4-oxadiazole(L),[Cu2L2(μ-Cl)2Cl2](1)and[CdL2(NO3)2](2)were synthesized and characterized by single crystal X-ray diffraction,IR,UV-Vis,fluorescence and TGA.Ligand L and complex 2 crystallize in monoclinic system.Complex 1 crystallizes in triclinic system.The space groups of compound L,complexes 1 and 2 are P21/c,P1 and C2/c,respectively.Complex 1 is a binuclear Cu(Ⅱ)complex bridged by two Cl atoms(Cl1,Cl1i)and has a distorted tetragonal pyramidal geometry with[CuCl3N2].Complex 2 has a distorted octahedral geometry with[CdN4O2].CCDC:1851091,L;1851090,1;1851089,2.
