Cd(Ⅱ)双苯吡唑基吡啶-草酸混配合物的合成、结构与性质
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。

Synthesis, Structure and Properties of the Cadmium Complex Using Bisphenyl-pyrazolyl-pyridine Derivative and Oxalate as Mixed Ligands
Abstract:
[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.
