The title compound, [Ag(C9H6NO)(C9H7NO)], crystallizes as a non-centrosymmetric polymorph. The structure was previously reported by Wu et al. [(2006). Acta Cryst. E62, m281–m282] in the centrosymmetric space group Pbcn. The AgI ion displays a distorted tetrahedral coordination geometry defined by two N and two O atoms from a neutral quinolin-8-ol ligand (HQ) and a deprotonated quinolin-8-olate anion (Q−). The dihedral angle between the two ligands is 47.0 (1)°. Strong O—H...O hydrogen bonds link the molecules into a supramolecular chain along the a-axis direction.
