摘要
利用3,4-吡唑二甲酸与硝酸锌作用合成了一种新的配合物[Zn(H_2pdc)_2(H_2O)_2]·2DMF,并采用红外光谱、元素分析和单晶-X衍射结构分析等手段对其进行了表征。晶体结构表明[Zn(H_2pdc)_2(H_2O)_2]·2DMF属于三斜晶系Pī空间群,该配合物中的锌离子位于八面体的配位环境中,[Zn(H_2pdc)_2(H_2O)_2](独立单元)和DMF间通过氢键的作用而形成一个二维的超分子结构,考察了该配合物的热稳定性和荧光性能。
A new metal complex[Zn(H_2pdc)_2(H_2O)_2]·2DMF(H_3pdc=3,4-pyrazoledicarboxylic acid)has been synthesized by the reaction of H_3pdc and Zn(NO_3)_2,and characterized by elemental analysis,IR spectra,and single-crystal X-ray diffraction.Structure analysis reveals that complex[Zn(H_2pdc)_2(H_2O)_2]·2DMF has mononuclear structure,each Zn(II)ion is located in an octahedron geometry,and independent units[Zn(H_2pdc)_2(H_2O)_2]and DMF are linked by intermolecularhydrogen bonds to form a 2D supramolecular network.The thermal stability and luminescent property of the complex in the solid state have also been investigated.
