| description | In the title complex, [Cu(C14H13N3O)(C14H12N3O)](CCl3COO), the central Cu(II) ion exhibits a distorted octahedral geometry with the two ligands coordinating in an meridional format. The N4O2 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. |
