Synthesis,Crystal Structure and Spectroscopic Characterization of a Heterometallic Cu-Zn Complex

在溶剂热条件下,利用配合物配体CuL与高氯酸锌反应,合成了一例新的异金属配合物[(CuL)2Zn(ClO4)2],其结构经X-射线单晶衍射、元素分析、红外光谱,紫外—可见光谱等表征.配合物属于单斜晶系,C2/c空间群.晶胞参数分别为a=1.5756(2)nm,b=1.7660(2)nm,c=1.5570(2)nm,α=90°,β=94.137(2),γ=90°.配合物通过分子间氢键连成一维链状结构.

A new heterometallic complex[（CuL）2 Zn （ClO4）2] was solvothermally synthesized by the reaction of a mononuclear complex ligand CuL with Zn（C104）2 · 6H2O. The complex was char- acterized by X-ray diffraction, elemental analysis, IR and UV-vis spectra. The complex crystallizes in the monoclinic system in space group C2/c with cell parameters of a=1. 5756（2） nm,b=1. 7660（2） nm,c=1. 5570（2） nm,α=90°,β=94. 137（2）,γ=90°. The neighboring trinuclear units are linked to form a one-dimensional chain structure by means of intermolecular hydrogen bonds.
