title: The non-centrosymmetric polymorph of (quinolin-8-ol-κ(2) N,O)(quinolin-8-olato-κ(2) N,O)silver(I).
abstract: 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 Ag(I) ion displays a distorted tetra-hedral 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 mol-ecules into a supra-molecular chain along the a-axis direction.
