In the title complex, [CoCl2(C21H19N3)], the CoII atom is coordinated by one pyridine and two imine N atoms and by two chloride anions in a distorted trigonal bipyramidal geometry. The structure exhibits a pseudo-mirror plane through the metal atom, two chloride anions and the pyridine ring. In the crystal structure, the complexes are connected via intermolecular C-H...Cl hydrogen bonding.
