Bis(1-phenyl-3-{(Z)-[phen-yl(pyridin-2-yl)methyl-idene]amino-κ²N,N'}urea-κO)nickel(II) dinitrate.
The Ni(II) atom in the title salt, [Ni(C₁₉H₁₆N₄O)₂](NO₃)₂, is N,N',O-chelated by two neutral Schiff base ligands in a distorted octa-hedral geometry. One nitrate ion inter-acts with the metal atom indirectly, in an outer-sphere type of coordination, through N-H⋯O hydrogen bonds; the other nitrate ion does not engage in any inter-actions and is equally disordered over two positions in the crystal.
