【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]。更多还原

【Abstract】 2-Methyl-5-(2-pyridyl)-1,3,4-oxadiazole(L), [Cu2 L2( μ-Cl)2 Cl2](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, Cl1 i) and has a distorted tetragonal pyramidal geometry with [CuCl3 N2]. Complex 2 has a distorted octahedral geometry with [CdN4 O2]. CCDC: 1851091, L; 1851090, 1; 1851089, 2.更多还原
