In the title complex, [Cu(C 14H 13N 3O) (C 14H 12N 3O)](CCl3COO), the central Cu(II) ion exhibits a distorted octa-hedral geometry with the two ligands coordinating in an meridional format. The N 4O 2 ligand environment is defined by two benzoyl O atoms, two pyridyl N atoms and imino N atoms. As evidenced by the bond lengths, the two benzohydrazone ligands exist in distinctively different forms, one of them as a regular neutral ligand and the other as an anionic enolate arising from deprotonation. The much longer Cu-O bond and longer Cu-N bond lengths in the neutral benzohydrazone ligand imply weak ligation in comparison with the anionic enolate form. The acute angles of the five-membered rings cause a significant deviation from a regular octahedral geometry.
