catena-Poly[[silver(I)-μ-4,4′-bipyridine-κ(2) N:N′] 4-[2-(4-carb­oxy­phen­yl)-1,1,1,3,3,3-hexa­fluoro­propan-2-yl]benzoate]

Assembly of the flexible dicarb­oxy­lic ligand 4-[2-(4-carboxyphenyl)-1,1,1,3,3,3-hexafluoropropan-2-yl]benzoate and 4,4′-bipyridine as co-ligand with Ag(I) ions resulted in the formation of the polymeric title compound, {[Ag(C(10)H(8)N(2))](C(17)H(9)F(6)O(4))}(n), in which the metal atoms are bridged by the 4,4′-bipyridine ligands, generating cationic chains extending along [010]. The dihedral angles between the benzene rings in the anion and the pyridine rings in the cation are 72.42 (9) and 9.36 (10)°, respectively. The mol­ecular conformation of the anion is stabilized by intra­molecular C—H⋯F hydrogen bonds. In the crystal, the anions inter­act with the cationic chains via C—H⋯O hydrogen bonds, forming layers parallel to (001), in which weak π–π stacking inter­actions [centroid–centroid distances = 3.975 (3)–4.047 (3) Å] involving the pyridine rings of adjacent 4,4′-bipyridine ligands are present. The planes are further assembled into a three-dimensional network by O—H⋯O hydrogen bonds.
