Diaquabis{2-hydroxy-5-[(pyridin-2-yl)methylideneamino]benzoato-κ2N,N′}zinc(II) dihydrate

Abstract

The complex molecule of the title compound, [Zn(C13H9N2O3)2(H2O)2]·2H2O, has 2 symmetry with the ZnII cation located on a twofold rotation axis. The Zn cation is N,N′-chelated by two 5-[(pyridin-2-yl)methylideneamino]-2-hydroxybenzoate anions and coordinated by two water molecules in a distorted octahedral geometry. Within the anionic ligand, the pyridine ring is oriented at a dihedral angle of 49.54 (10)° with respect to the benzene ring. The carboxylate group of the anionic ligand is not involved in coordination but is O—H...O hydrogen bonded to the coordinated and uncoordinated water molecules. Weak intermolecular C—H...O hydrogen bonding is also present in the crystal structure.
