Abstract

The title compound, [Ag(C9H10NO3)] n , is a polymeric silver(I) complex of l-tyrosine. The Ag(I) atom is connected to N and O atoms of two different l-tyrosine ligands in an almost linear arrangement, with an N(i)-Ag-O1 bond angle of 173.4 (2)° [symmetry code: (i) x + 1, y, z]. The Ag-N(i) and Ag-O bond lengths are 2.156 (5) and 2.162 (4) Å, respectively. The polymeric chains extend along the crystallographic a axis. Strong hydrogen bonds of the N-H⋯O and O-H⋯O types and additional C-H⋯O inter-actions connect these chains into a double-layer polymeric network in the ab plane.

Keywords: crystal structure; hydrogen bonding; l-tyrosinate; one-dimensional silver(I) coordination polymer.
