Crystal structure of catena-poly[bis­[μ(3)-2-(2-nitro­phen­yl)acetato-κ(3) O:O:O′]disilver(I)]

The title compound, [Ag(2)(C(8)H(6)NO(4))(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 Ag(I) ions, 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 the a-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.
