trans-Bis{2-[3-(cyclohexylamino)propyliminomethyl]phenolato}nickel(II) dinitrate

The title compound, [Ni(C16H24N2O)(2)](NO3)(2), is a mononuclear nickel(II) compound. The Ni II atom is coordinated by two N atoms and two O atoms from the Schiff base ligands. The four atoms around the metal are coplanar, constituting a slightly distorted square-planar geometry. The complex is located on an inversion center. All of the nitrate O atoms and all amine N atoms in the Schiff base ligands contribute to hydrogen bonds, leading to the formation of a three-dimensional network.
