摘要通过三(3-氨基丙基)胺与5-R-2-甲氧基-1,3-苯二醛(R = CH3O,CH3或Br)的模板缩合反应合成了三种双核银(I)加密物,并通过物理测量进行了表征(溶液电导率,1H NMR,IR和电子光谱)。L1(R = CH3O)的穴状晶体的晶体结构是通过X射线衍射确定的,并为阳离子[Ag2L1] 2+提供了一种新颖的篮子结构,其中两个银(I)中心都具有三个配位环境。晶体是单斜晶体,空间群Cc,C48H68Cl2N8O15Ag2,Mr = 1283.75,a = 11.349(2),b = 29.16(1),c = 17.506(6)A,β= 102.38(2)°,Z = 4,R对于3693次反射,= 0.063和Rw = 0.071。每个Ag原子位于一个由一个桥头叔氮和两个亚氨基氮组成的平面三角形扭曲的三角锥的顶部。穴状配位体的仅两个桥接链与金属配位,而另一个则不配位。核间距Ag(1)···Ag(2)为7
