In the title compound, [Zn(C(10)H(11)N(2)O(2))(2)(C(5)H(5)N)(2)], the Zn(II) atom lies on an inversion centre, and is coordinated in a distorted octa-hedral geometry by two carbonyl O atoms and two imino N atoms from two anionic bidentate acetone (2-hydroxy-benzo-yl)hydrazone ligands and by two N atoms from two pyridine mol-ecules. The hydroxyl group acts as a donor, forming an intra-molecular O-H⋯N hydrogen bond.
