Poly[4-(dimethylamino)pyridinium [(μ6-5-carboxybenzene-1,2,4-tricarboxyato-κ6 O 1:O 1′:O 2:O 4:O 4′:O 5)diargentate(I)]]

چکیده
In the title compound, {(C(7)H(11)N(2))[Ag(2)(C(10)H(3)O(8))]}(n), the polymeric anion consists of two Ag(I) atoms and a Hbtc(3-) ligand (H(4)btc = benzene-1,2,4,5-tetra-carboxylic acid). Each Ag(I) atom is coordinated by four O atoms from three different Hbtc(3-) ligands. The two Ag(I) atoms are bridged by two bidentate carboxyl-ate groups into an Ag(2)O(4) cyclic unit, with an Ag⋯Ag distance of 2.8189 (3) Å. In this way, the Ag atoms are connected by the Hbtc(3-) 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-(dimethyl-amino)pyridine] is trapped in the network and adheres to the layer by an N-H⋯O hydrogen bond.
