    Abstract

    Mononuclear and binuclear manganese Schiff base complexes containing substituted N,N′-bis(salicylidene)propane-1,3 -diamine ligands, H2(Rsalpn) (R = 5-Br, 3,5-Br and 3,5-Cl), have been prepared and characterised by elemental analyses, IR and EPR spectroscopy, FAB and LDI-TOF mass spectrometry, cyclic voltammetry and magnetic measurements. The structure of [Mn(3,5-Brsalpn)O]2·2DMF (5) has been determined by X-ray diffraction techniques. The compound has a dimeric structure with μ-oxo bridges and the ligand spanning both metal centres. The capacity of the complexes to oxidise phenothiazine and their ability to catalyse the photolysis of water have also been studied. © 2001 Elsevier Science B.V.
