Abstract
A new coordination polymer {[Ag4(L)3(nip)2](H2O)}n(L = 1,4-bis(5,6-dimethylbenzimidazol-1-yl)butane, H2nip = 5-nitroisophthalic acid) is hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction. The complex features a 3D sqc117 supramolecular framework based on unique tetranuclear Ag(I) clusters which involve the ligand-supported Ag-Ag interactions.
