利用水热法合成了基于不对称三氮唑衍生物配体Hptp(Hptp=2-(5-(pyridin-3-yl)-1H-1,2,4-triazol-3-yl)pyrazine)的3个配合物[Cd2(ptp)2(SO4)(H2O)2]n(1)、[Zn(ptp)2(H2O)2](2)和[Cd(ptp)2(H2O)2](3),它们的结构通过元素分析,红外,粉末X射线衍射和X射线单晶衍射表征.配合物1中,配体ptp-和Cu2+形成波浪状的一维结构,这些一维链通过SO42-链接形成三维结构.配合物2和3是同构化合物,单核单元在分子间氢键的作用下形成超分子二维平面.光催化降解实验表明,在双氧水存在时配合物1～3在60 min内使亚甲基蓝的降解率分别达到79％、81％和88％.%Three coordination complexes,namely [Cd2(ptp)2(SO4)(H2O)2]n (1),[Zn(ptp)2(H2O)2] (2) and [Cd(ptp)2 (H2O)2] (3) (Hptp=2-(5-(pyridin-3-yl)-1H-1,2,4-triazol-3-yl)pyrazine),have been synthesized and characterized by elemental analyses,infrared spectra and single-crystal X-ray diffraction analyze.In complex 1,corrugated 1D chains constructed by the ptp-and Cd2+ were connected by SO42-to form a 3D structure.In isostructural complexes 2 and 3,intermolecular O-H …N hydrogen bonds link the mononuclear molecules into plane superstructure.The photocatalytic experiment result indicates that in the presence of H2O2,the degradation ratios of methylene blue (MB) reach to 79％,81％ and 88％,respectively,when complexes 1,2 and 3 act as catalyst.
