In the title compound, [Ag(C(16)H(10.5)NO(2))(2)], the Ag(I) cation (site symmetry 2) is coordinated by two N atoms in a near-linear AgN(2) arrangement. Two carboxyl-ate O atoms from two additional 2-phenyl-quinoline-4-carboxyl-ate ligands form long Ag-O bonds [2.6585 (17) Å], resulting in a distorted square-planar arrangement. The bridging ligands result in infinite corrugated sheets propagating in (010). An O-H⋯O hydrogen bond, disordered about a twofold axis, completes the structure.
