Catena-Poly[[silver(I)-?-4,4'-bipyridine-?(2)N:N'] 4-[2-(4-carb-oxy-phen-yl)-1,1,1,3,3,3-hexa-fluoro-propan-2-yl]benzoate].

ABSTRACT: Assembly of the flexible dicarb-oxy-lic 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 mol-ecular conformation of the anion is stabilized by intra-molecular C-H?F hydrogen bonds. In the crystal, the anions inter-act with the cationic chains via C-H?O hydrogen bonds, forming layers parallel to (001), in which weak ?-? stacking inter-actions [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.
