complexes were synthesized and structurally characterized. Crystals of [Ag(dafone)2]NO3 · H2O (1) contain two strictly planar four-coordinate Ag(I) complexes. The silver coordination polyhedron in [Ag2(4,4′-bpy)(dafone)4]BF4 (2) is a highly distorted tetrahedron. Its crystal structure is built by a two-fold interpenetration of identical porous networks. The unusual coordination in the two compounds (planar
合成了两个
银(I)与
4,5-二氮杂芴-9-一(重酮)的络合物,这是Ag-重酮络合物的第一个实例,并对其结构进行了表征。[Ag(dafone)2 ] NO 3 ·H 2 O(1)晶体包含两个严格平面的四坐标Ag(I)配合物。[Ag 2(4,4'-bpy)(dafone)4 ] BF 4(2)中的
银配位多面体是高度变形的四面体。它的晶体结构是由两个相同的多孔网络互穿而成。这两种化合物在(不寻常的协调平面四坐标d 10在离子1,螯合,在两个长的Ag-N键2和在两种复合低键价和)是部分由于dafone的大螯合物咬合,并且部分由于堆叠和影响Ag的配位几何形状的其它分子间的相互作用(一世)。通过使用DFT计算的[Ag(N–N)2 ] +配合物的分子模拟进一步探讨了这一点。
