摘要:
Mononuclear and binuclear manganese Schiff base complexes containing substituted N,N ' -bis(salicylidene)propane-1,3-diamine ligands, H-2(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 mu -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. (C) 2001 Elsevier Science B.V. All rights reserved.
