Crystal structure ofcatena-poly[silver(I)-μ-L-valinato-κ²N:O]

The reaction of Ag2O with L-valine (L-Hval, C5H11NO2) in a 1:2 molar ratio in water, followed by vapour diffusion, afforded a coordination polymer of the title compound, [Ag(C5H10NO2)]n, with N—Ag—O repeat units, which is classified as a type III silver(I) complex with amino acid ligands. The asymmetric unit consists of two independent units of [Ag(L-val)]. In the crystal, the polymeric chains run along [101], and neighbouring chains are linkedviaa weak Ag...Ag interaction and N—H...O hydrogen bonds. The title complex exhibited antimicrobial activity against selected bacteria (Escherichia coli,Bacillus subtilis,Staphylococcous aureusandPsedomonas aeruginosa).
