Özet
A polymeric silver(I) complex, [Ag-4(-pydc)(2)(-pm)(2)](n) (1) (pydc=pyridine-3,5-dicarboxylate and pm=pyrimidine), has been synthesized and characterized by elemental analysis, IR spectroscopy, thermal analysis, and single-crystal X-ray diffraction. X-ray crystallographic data of 1 revealed that pydc exhibits two different coordinaton modes that play a key role in the construction of the 3-D crystal network including Ag-carboxylate clusters in which close Ag-Ag distances exist. The magnitudes of close Ag-Ag interactions in second-order energy (E-2) have been revealed by natural bond orbital analysis performed with single point energy calculation using the experimental geometry of 1. Furthermore, the luminescent properties of 1 show strong fluorescence with two emission maxima in the visible region. Also, 1 has antifungal activity on Candida albicans (MIC value, 4gmL(-1)) and good antibacterial activity on micro-organisms (MIC value, 64-256gmL(-1)).
