Abstract
In the title compound, {(C7H11N2)[Ag2(C10H3O8)]}n, the polymeric anion consists of two AgI atoms and a Hbtc3− ligand (H4btc = benzene-1,2,4,5-tetracarboxylic acid). Each AgI atom is coordinated by four O atoms from three different Hbtc3− ligands. The two AgI atoms are bridged by two bidentate carboxylate groups into an Ag2O4 cyclic unit, with an Ag⋯Ag distance of 2.8189 (3) Å. In this way, the Ag atoms are connected by the Hbtc3− ligands into an extended two-dimensional layer structure. A three-dimensional network is accomplished through O—H⋯O hydrogen bonds between the anionic layers. The cationic guest Hdmap+ [dmap = 4-(dimethylamino)pyridine] is trapped in the network and adheres to the layer by an N—H⋯O hydrogen bond.
