摘要

The title compound, Ag2(C8H6NO4)2n, is a silver complex of 2-(2-nitro#173;phen#173;yl)acetic acid. The mol#173;ecules are not conventional crystallographic inversion dimers but consist of two independent ligands and two AgI ions, each with a distorted T-shaped coordination environment. The dihedral angles between acetate groups and the benzene rings are 51.1#8197;(2) and 57.9#8197;(2)#176;. The nitro groups are oriented at dihedral angles of 23.6#8197;(5) and 32.3#8197;(3)#176; with respect to the parent benzene rings. The dimers form polymeric chains along the a-axis direction. The Ag#8943;Ag separation within a dimer is 2.8200#8197;(5) and between symmetry-related dimers is 3.6182#8197;(5)#8197;#197;. The polymeric chains are inter#173;linked by C#8212;H#8943;O hydrogen-bond inter#173;actions.
