含草酰胺桥大环三核配合物的合成、结构及性质研究

Synthesis,Structure and Properties of an Oxamido-bridged Macrocyclic Trinuclear Complex

以一个草酰胺大环铜配合物为前驱体,设计合成了一个新颖的三核配合物,并对其进行了元素分析、红外光谱,电子顺磁共振以及 X 射线单晶衍射等表征.晶体结构解析表明:该配合物的组成为[Cr(CuL)_2(C_2H_5OH)_2](ClO_4)_3.配合物属于三斜晶系,P-1空间群.晶胞参数为a=0.918 44(11)nm,b=1.307 90(16)nm,c=1.539 01(18)nm,a=98.389(2)°,β=90.112(2)°,γ=105.312(2)°,F(000)=789,R_1=0.094 0,wR_2=0.241 3.

By using a macrocyclic oxamide-Cu （ Ⅱ ） complex ligand as precursor, a novel trinuclear complex （CuL） 2 （C2H5OH）2] （ClO4） 3 has been prepared and characterized by X-ray diffraction analysis. The complex belongs to triclinic, space group P-1 with a=0. 918 44（11） nm, b=1. 307 90（16） nm, c=1. 539 01（18） nm, α=98. 389（2）°, β=90. 112（2）°, γ=105. 312 （2）°, F（000）=789, R1=0. 094 0, wR2=0. 241 3. Their spectroscopic properties are also investigated and the EPR spectra have been simulated by WINEPR and SimFonia programs.
