determinations of the isostructural compounds ZrCl4·2PriHNCMeCHCMeO and TiCl4·2PriHNCMeCHCMeO indicated an octahedral co-ordination environment around the metal with the trans monodentate N–O ligands bound through the oxygen only. Strong intramolecular hydrogen bonding of the hydrogen on the nitrogen with the ligand oxygen is consistent with a ligand immonium enolate structure. An X-ray study of the
