The synthesis and characterisation of foul monomeric cis-dioxomolybdenum(VI) complexes involving Schiff base ligands is described. Ligands were obtained by condensation of salicylaldehyde with substituted aminoethanols. [MoO2(acac)(2)] reacted with the prepared ligands forming six-coordinated cis-dioxoMo(VI) complexes. X-ray diffraction studies confirmed that ligands act in a tridentate manner and the sixth coordination site around Mo(VI) is occupied by methanol used as solvent. The complexes act as inhibitors in the oxidation of aldehydes by oxygen. (C) 2000 Elsevier Science Ltd All rights reserved.
