Crystal structure ofcatena-poly[bis[μ3-2-(2-nitrophenyl)acetato-κ3O:O:O′]disilver(I)]

Abstract

The title compound, [Ag2(C8H6NO4)2]n, is a silver complex of 2-(2-nitrophenyl)acetic acid. The molecules are not conventional crystallographic inversion dimers but consist of two independent ligands and two AgIions, each with a distorted T-shaped coordination environment. The dihedral angles between acetate groups and the benzene rings are 51.1 (2) and 57.9 (2)°. The nitro groups are oriented at dihedral angles of 23.6 (5) and 32.3 (3)° with respect to the parent benzene rings. The dimers form polymeric chains along thea-axis direction. The Ag...Ag separation within a dimer is 2.8200 (5) and between symmetry-related dimers is 3.6182 (5) Å. The polymeric chains are interlinked by C—H...O hydrogen-bond interactions.
