Three Coordination Complexes Based on an Asymmetric Triazole Derivative Ligand:Syntheses, Structures and Photocatalytic Properties

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） （H20）2]n （1）, [Zn （ptp）2 （H20）2] （2） and [Cd （ptp）2 （H2O）2] （3） （Hptp=2-（5-（pyridin-3-yl）-lH-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.
