The title molecule, [Ni(C10H12N3O3)2], possesses a crystallographic centre of symmetry at the NiII atom. The coordination geometry around the NiII atom is distorted square planar, consisting of four N atoms from two oxime ligands. The crystal packing shows two-dimensional polymeric chains, which are stabilized by a hydrogen-bonded network, and other weak intermolecular interactions.
