Bis(μ-4-chlorobenzoato-κ2O:O′)bis[(2-aminopyridine-κN)silver(I)](Ag—Ag) monohydrate

Abstract

The title complex, [Ag2(C7H4ClO2)2(C5H6N2)2]·H2O, lies about an inversion center, with the water molecule on a twofold rotation axis, and the AgI atom is three-coordinated by two O atoms from two different but symmetry-related 4-chloro­benzoate anions and one N atom from one 2-amino­pyridine ligand. The 4-chloro­benzoate anion acts as a bidentate ligand, bridging two inversion-related Ag atoms of the complex and forming a dimer. In the crystal structure, the mol­ecules are linked through intramolecular and intermolecular N—H⋯O and O—H⋯O hydrogen bonds, forming two-dimensional layers parallel to the bc plane.
