Abstract: The trinuclear nickel(II) title compound, [Ni₃(C₁₅H₁₂N₂O₄)₂(C₅H₅N)₂(C₃H₆NO)₂], possesses a crystallographically imposed centre of symmetry. The central Ni atom adopts an axially elongated octahedral geometry, involving two N and two O atoms from two phenoxyacetylsalicylhydrazidate ligands in the equatorial plane and two O atoms from two dimethylformamide molecules in the axial positions. The inversion-related outer Ni atoms have square-planar coordination environments provided by two O atoms and one N atom of a phenoxyacetylsalicylhydrazidate ligand and by the N atom of a pyridine molecule. The shortest metal-metal separation is 4.6038 (11) Å. The molecular structure is stabilized by intramolecular C-HO hydrogen-bonding interactions.
