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%。
The asymmetric triazole-based ligands Hptp (Hptp = 2- (5- (pyridin-3-yl) -1H-1,2,4-triazol-3-yl) pyrazine were synthesized by hydrothermal method Three complexes [Cd2 (ptp) 2 (SO4) (H2O) 2] n (1), [Zn (ptp) 2 (H2O) 2] and [Cd (ptp) 2 (H2O) 2] 3) whose structures are characterized by elemental analysis, infrared, powder X-ray diffraction and X-ray single crystal diffraction. In complex 1, the ligands ptp- and Cu2 + form wavy one-dimensional structures, and these one-dimensional chains form three-dimensional structures via SO42-linkage. Complex 2 and 3 are isomorphic compounds, mononuclear units form a supramolecular two-dimensional plane under the intermolecular hydrogen bonding. Photocatalytic degradation experiments showed that the degradation rates of methylene blue reached 79%, 81% and 88% respectively in 60 min when complexes 1 ~ 3 were present in the presence of hydrogen peroxide.
