The title compound, [Ni(C10H11N4O5)2], contains asymmetric Schiff base ligands. The coordination sphere around the Ni atom is a distorted octahedron, with an average Ni-O distance of 2.072 (2) Å and Ni-N distances ranging from 2.059 (2) to 2.084 (3) Å. Bond angles at the Ni atom have values between 83.80 (9) and 96.93 (9)°. The structure is stabilized through an intermolecular hydrogen-bonding network.
