Abstract: In the title complex, [Co(C₁₀H₁₁N₂O₂)₂(C₅H₅N)₂], the Co^II atom lies on a centre of symmetry and adopts a distorted cis-CoO₂N₄ octahedral geometry. The two acetone salicyloylhydrazone ligands are deprotonated and act as N,O-bidentate monoanionic ligands, forming the equatorial plane, while the axial positions are occupied by two N atoms of two pyridine molecules. The complex presents O-HN and C-HN intramolecular hydrogen bonds. Intermolecular C-HN and C-HO interactions are also present in the crystal.
