摘要

采用Na6[Re4As2S2(CN)12]·0.75CH3OH·6H2O四面体簇氰基配合物与AgCN、NaCN和bpy（2,2′-联吡啶）在水溶液中反应制备了Na2[{Ag(bpy)2}{Ag(H2O)}{Ag3(bpy)2(μ-CN)}{Re4As2S2(CN)12}]·2.75H2O单晶。所获得的化合物是基于四面体簇阴离子和Ag(I)的配位聚合物的第一个例子。在其结构中，由于大量的CN基团和As-Ag键桥，形成了三维层。3D超分子网络还通过弱分子间相互作用、通过bpy配体的π⋯π相互作用和亲银Ag⋯Ag相互作用来稳定。该结构包含5个晶体独立的银原子，配位数分别为3,4,5。

First Example of a Coordination Polymer Based on a Tetrahedral Cluster Cyano Complex of Re, Ag(I), bpy

Single crystals of Na₂[{Ag(bpy)₂}{Ag(H₂O)}{Ag₃(bpy)₂(μ-CN)}{Re₄As₂S₂(CN)₁₂}]·2.75H₂O are prepared by the reaction of the Na₆[Re₄As₂S₂(CN)₁₂]·0.75CH₃OH·6H₂O tetrahedral cluster cyano complex, AgCN, NaCN and bpy (2,2′-bipyridine) in an aqueous solution. The obtained compound is the first example of a coordination polymer based on a tetrahedral cluster anion and Ag(I). In its structure, 3D layers are formed due to numerous bridges of CN groups and As–Ag bonds. The 3D supramolecular networks are additionally stabilized by weak intermolecular interactions, π⋯π interactions via bpy ligands, and argentophilic Ag⋯Ag interactions. The structure contains five crystallographically independent Ag atoms with coordination numbers 3, 4, 5.
