Crystal structure of catena-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 linked via a weak Ag⋯Ag inter­action and N—H⋯O hydrogen bonds. The title complex exhibited anti­microbial activity against selected bacteria (Escherichia coli, Bacillus subtilis, Staphylococcous aureus and Psedomonas aeruginosa).
