e. The structure of complex 1 possesses a one-dimensional ladderlike chain with guest 4,4'-bipy molecules, while the molecular structure of complex 2 is a dimeric species with a coordinating 4,4'-bipy ligand. Complex 3 consists of a one-dimensional ladderlike chain with monodentate 4,4'-bipyridine but somewhat different from that of complex 1. Complex 4 is a two-dimensional layer structure. In 1-4
四个结构上不同的复合物,[Pb(Hssal)(2,2'-bipy)](4,4'-bipy)0.5} n(1),[Pb2(Hssal)2(2,2'-bipy)2 (4,4'-bipy)(H2O)2](2),[Pb(Hssal)(phen)(4,4'-bipy)0.5] n(3)和[Pb(Hssal)(2,2 '-bipy)(bpe)0.5] n(4)已合成,并通过元素分析,IR,热重分析,荧光光谱和单晶X射线分析进行了表征,其中Hssal2-是双去质子化的5-磺基水杨酸酯, 2,2'-联吡啶是2,2'-联吡啶,phen是1,10-菲咯啉,4,4'-联吡啶是4,4'-联吡啶,bpe是反式1,2-双(4-吡啶基) )乙烯。配合物1的结构具有带有客体4,4'-bipy分子的一维梯状链,而配合物2的分子结构是具有配位的4,4'-bipy配体的二聚体。配合物3由具有单齿4,4'-联吡啶的一维梯状链组
