Bis{2-[3-(cyclohexylaminio)propyliminomethyl]-4-nitrophenolato}dimethanolnickel(II) dinitrate dihydrate

In the title complex, [Ni(C16H23N3O3)(2)(CH4O)(2)(NO3)(2)(.)-2H2O, a mononuclear centrosymmetric nickel(II) compound, the Ni II atom is six-coordinated in an octahedral geometry by two imine N and two phenolate O atoms from two Schiff base ligands, and by two O atoms from two coordinated MeOH molecules. In the crystal structure, the molecules are linked through intermolecular O-H..O-., N - H ... O and N - H ... N type hydrogen bonds, forming layers parallel to the bc plane.
