In the title complex, [Co(C10H11N2O2)2(C5H5N)2], the CoII 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-H...N and C-H...N intramolecular hydrogen bonds. Intermolecular C-H...N and C-H...O interactions are also present in the crystal.
