Diaqua-bis-{2-hy-droxy-5-[(pyridin-2-yl)methyl-idene-amino]-benzoato-?N,N'}zinc(II) dihydrate.

ABSTRACT: The complex mol-ecule 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)methyl-idene-amino]-2-hy-droxy-benzoate anions and coordinated by two water mol-ecules in a distorted octa-hedral 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 carboxyl-ate group of the anionic ligand is not involved in coordination but is O-H?O hydrogen bonded to the coordinated and uncoordinated water mol-ecules. Weak inter-molecular C-H?O hydrogen bonding is also present in the crystal structure.
