Bis(1-phenyl-3-{(Z)-[phen­yl(pyridin-2-yl)methyl­idene]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 octa­hedral geometry. One nitrate ion inter­acts 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 inter­actions and is equally disordered over two positions in the crystal.
