Bis(-4-chlorobenzoato-²O:O')bis[(2-aminopyridine-N)silver(I)](Ag-Ag) monohydrate

Z.-L. You, H.-L. Zhu and W.-S. Liu

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 Ag^I 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-HO and O-HO hydrogen bonds, forming two-dimensional layers parallel to the bc plane.
