In the title compound, [Ni(C9H9N4O2)2], the NiII ion is situated on a twofold rotation axis and is coordinated by two O and four N atoms from two tridentate {2-amino-2-oxo-N-[(1E)-1-(pyridin-2-yl-[kappa]N)ethylidene]acetohydrazidate ligands in a distorted octahedral geometry. In the crystal, N-H...O and N-H...N hydrogen bonds link the molecules into columns in [001]. The porous crystal packing is further stabilized via [pi]-[pi] interactions between the pyridine rings of neighbouring molecules [centroid-centroid distance = 3.746 (3) Å] with voids of 270 Å3.
