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(C2H5OH)2](ClO4)3.配合物属于三斜晶系,P-1空间群.晶胞参数为a=0.91844(11)nm,b=1.30790(16)nm,c=1.53901(18)nm,α=98.389(2)°,β=90.112(2)°,γ=105.312(2)°,F(000)=789,R1=0.0940,wR2=0.2413.
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.
