Abstract
A silver(I) complex of arginine (arg), [Ag(arg)]NO3•0.5H2O (1) was prepared and characterized by elemental analysis, IR and NMR spectroscopy, and X-ray crystallography. The IR and NMR spectroscopic data confirmed the coordination of the ligand to silver(I). The structure of 1 shows that it is polymeric with each silver atom bound to the carboxyl O atom of one arginine ligand and to the amino N atom of another adopting a linear coordination environment. The two coordinate N–Ag–O units are repeated to form infinite chains. The molecular structure is stabilized by N–H…O and C–H…O hydrogen bonds. Antimicrobial activities of the complex were evaluated by minimum inhibitory concentration against gram-negative bacteria (E. coli, P. aeruginosa), molds (A. niger, P. citrinum) and yeasts (C. albicans, S. cerevisiae).
