2-羟基-1-萘甲醛半碳酰腙铬(Ⅲ)配合物的合成和晶体结构(英文)

Synthesis and Crystal Structure of the Chromium(Ⅲ) Complex with 2-hydro-1-naphthaldehyde Semicarbazone

本文合成了2-羟基-1-萘甲醛半碳酰腙铬(Ⅲ)单核配合物,通过红外、紫外、荧光光谱和单晶X-射线衍射等方法对其结构进行了表征。其晶体结构属于单斜晶系,空间群C2/c。光谱数据表明:配体2-羟基-1-萘甲醛半碳酰腙作为三齿螯合剂,通过酚氧,亚胺基氮和酮氧与铬(Ⅲ)离子配位。其铬(Ⅲ)中心为扭曲的六配位八面体几何构型。

The mononuclear chromium（Ⅲ） complex with 2-hydroxy-1-naphthaldehyde semicarbazone was synthesized and characterized by IR,UV-Vis,fluorescence spectra and single-crystal structure determination.The crystal structure belongs to monoclinic system,space group C2/c with a=3.535 7（8） nm,b=1.608 5（4） nm,c=0.930 52（19） nm,β=98.271（4）°,and Z=8.The crystal structure and spectra data suggest that the ligand of 2-hydro-1-naphthal-dehyde semicarbazone behaves as a tridentate chelating agent,coordinating through phenolic oxygen,nitrogen atom of C=N group and ketonic oxygen.The chromium（Ⅲ） center is a six-coordinated distorted octahedral geometry.
