Abstract: The asymmetric unit of the crystal structure of the title complex, [Ni(C₁₈H₁₂N₂O₃)(C₅H₅N)₃]·3C₅H₅N, contains two independent Ni^II complex molecules and six uncoordinated pyridine molecules. Each Ni^II atom is coordinated by two O and four N atoms, from three pyridine and a chelating 3-hydroxy-N'-(2-oxidobenzylidene)-2-naphthohydrazide dianionic ligand, with a distorted octahedral geometry. Intramolecular O-HN hydrogen bonding exists in both complex molecules but no intermolecular hydrogen bonding is observed in the crystal structure.
