| 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]。 |

| Abstract: 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]. |
