A three-dimensional supra­molecular framework of silver(I), 2-phenyl­quinoline-4-carboxyl­ate and 4,4'-bi­pyridine

A novel supra­molecular framework, catena-poly[[[aqua(2-phenyl­quinoline-4-carboxyl­ato-[kappa]O)silver(I)]-[mu]-4,4'-bipyridine-[kappa]²N:N'] dihydrate], {[Ag(C₁₆H₁₀NO₂)(C₁₀H₈N₂)(H₂O)]·2H₂O}_n, has been synthesized and structurally characterized. The Ag^I centres are four-coordinated and bridged by 4,4'-bi­pyridine (4,4'-bipy) ligands to form a one-dimensional Ag-bipy chain. The Ag-bipy chains are further linked together by inter­molecular O-H...O and O-H...N hydrogen-bonding inter­actions between adjacent chains, resulting in a three-dimensional framework.
