摘要
通过自组装的方法得到了对称的均双核配合物Cu2(fsa)2en(H2O).5H2O,其中(fsa)2en为二(3-羧基水杨醛叉)缩1,2-乙二胺的对称双Sch iff碱配体,并用单晶X-ray衍射法测定其晶体结构.结果表明该晶体属正交晶系,空间群Pbca,晶胞参数:a=1.608 6(3)nm,b=1.336 3(3)nm,c=2.065 0(4)nm,α=90°,β=90°,γ=90°,Z=8,R1=0.048 3,wR2=0.096 8.配合物中两个Cu(Ⅱ)通过酚氧原子桥联在一起.
The homobinuclear complex Cue(fsa)2en(H2O)·5H2O, where (fsa) 2en is the schiff base N, N'-bis(3-carboxylsalicylidene) ethylenediamine, was obtained by self-assembly method. Its crystal structure was determined by X-ray analysis. The crystal belongs to orthohombic system, space group Pbca, a=1.6086(3)nm,b=1.3363(3)nm,c=2.0650(4)nm,d=900,β=90°,y=90°,Z=8,R1=0.0483,wR2=0.0968. The structure is made of binuclear units, in which two copper atoms are bridged by two phenolic oxygen atoms.
