The complex molecule of the title compound, [Ni(C₁₀H₁₁N₂O)₂(C₅H₅N)₂], has a crystallographically imposed centre of symmetry. The Ni^II atom is coordinated in a distorted octahedral geometry by the O and N atoms of two trans arranged anionic bidentate hydrazone ligands forming the equatorial plane and by the N atoms of two pyridine molecules at the axial positions. In the crystal, intermolecular C-HN hydrogen bonds link the molecules into columns parallel to the b axis.
