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

The complex mol­ecule of the title compound, [Zn(C(13)H(9)N(2)O(3))(2)(H(2)O)(2)]·2H(2)O, has 2 symmetry with the Zn(II) 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.
