Diaqua­bis­{2-hy­droxy-5-[(pyridin-2-yl)methyl­idene­amino]­benzoato-κ2 N,N′}nickel(II) dihydrate


In the title complex, [Ni(C(13)H(9)N(2)O(3))(2)(H(2)O)(2)]·2H(2)O, the Ni(II) atom, located on a twofold rotation axis, is in a distorted octa-hedral geometry, defined by four N atoms from two 2-hy-droxy-5-[(pyridin-2-yl)methyl-idene-amino]-benzoate ligands and two O atoms from two water mol-ecules. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the complex mol-ecules and uncoordinated water mol-ecules into a three-dimensional network. Intra-molecular O-H⋯O hydrogen bonds are present between the hy-droxy and carboxyl-ate groups.
