Tetraaquabis(2-methoxybenzaldehyde isonicotinoylhydrazone)cadmium(II) dinitrate.

The Cd(II) centre in the title complex, [Cd(C(14)H(13)N(3)O(2))(2)(H(2)O)(4)](NO(3))(2), occupies a crystallographic inversion centre and is coordinated by two donor N atoms from two 2-methoxybenzldehyde isonicotinoylhydrazone ligands and by four O atoms from four coordinated water molecules, giving a slightly distorted octahedral geometry. There is an extended three-dimensional network structure resulting from O-H...O hydrogen bonds between coordinated water and nitrate anions, and between coordinated water and carbonyl O atoms, and from N-H...O hydrogen bonds between NH groups and nitrate O atoms.
