摘　　要：合成了Cd(Ⅱ)与类蝎型吡唑衍生物和草酸的混合配体的配合物[Cd2(HL)2(ox)].1.5H2O(H2L=2,6-二(5-苯基-吡唑-3-基)吡啶,H2ox=草酸)。通过元素分析、红外光谱、紫外光谱、X射线粉末衍射(PXRD)和X射线单晶结构分析确定了配合物的结构。配合物晶体属于三斜晶系、P-1空间群,Cd(Ⅱ)是六配位,由一个ox2-基中的2个O原子和来自2个HL-中的4个N原子配位,构成变形八面体配位构型,而相邻Cd(Ⅱ)原子间均通过HL-上的N原子和草酸根分别连接形成2条互不相交的一维无限链状结构。性质测试结果表明,该配合物具有良好的热稳定性和荧光特性,对环己烷氧化反应也具有一定的催化活性。[Cd2（HL）2（ox）]·1.5H2O was synthesized hydrothermally from Cd（NO3）2·4H2O,pyrazolyl derivative（H2L=2,6-di-（5-phenyl-1H-pyrazol-3-yl）pyridine） and oxalate（H2ox=oxalic acid）.Structural analysis revealed that the complex crystallized in the triclinic system with P-1 space group.The Cd took a distorted octahedral geometry and was coordinated by two oxygen atoms from one ox ligand and four N atoms from two HL-ligands.Adjacent Cd atoms（Cd1/Cd2） were connected through bridging ox ligand and N atoms from HL-to generate two separate 1D chains structure.The complex was further characterized by elemental analysis,IR,UV-Vis spectroscopy and powder X-ray diffraction（PXRD）.In addition,the complex displayed ideal thermal stability and photoluminescent properties,and exhibited some catalytic activity toward the oxidation of cyclohexane.
