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) A. The mol­ecular structure is stabilized by intra­molecular C—H⋯O hydrogen-bonding inter­actions.
