Tetra­aqua­bis­[N,N′-bis­(pyridin-3-yl­methyl­idene)benzene-1,4-diamine]­zinc dinitrate 1.49-hydrate

In the title compound, [Zn(C(18)H(14)N(4))(2)(H(2)O)(4)](NO(3))(2)·1.49H(2)O, the Zn(II) atom, lying on an inversion center, is coordinated by two N atoms from two N,N′-bis­(pyridin-3-yl­methyl­idene)benzene-1,4-diamine ligands and four water mol­ecules in a distorted octa­hedral geometry. The nitrate anion is disordered over two sets of sites, with an occupancy ratio of 0.744 (4):0.256 (4). The uncoordinated water mol­ecule is also disordered with an occupancy factor of 0.744 (4). O—H⋯O and O—H⋯N hydrogen bonds link the complex cations, nitrate anions and uncoordinated water mol­ecules into a supra­molecular layer parallel to (102).
