Syntheses and Characterisation of Manganese(III) Perchlorate Complexes with Unsymmetrical Schiff Bases
摘要:
A series of unsymmetrical tridentate dianionic Schiff bases derived from substituted salicylaldehyde and ethanol and propanolamine were prepared and characterised by elemental analyses, IR and H-1 NMR spectroscopy. The interaction of these bases with Mn(ClO4)(2).6H(2)O has been studied, leading to the preparation of manganese(III) perchlorate complexes. All the Schiff base ligands H2L yield 1:1 compounds [MnL(H2O)(2)]ClO4.nH(2)O (n = 1 - 3). The resultant complexes were characterised by elemental analyses, IR spectroscopy and magnetic measurements.
