Synthesis, structure and antibacterial activity of manganese(III) zomplexes of a Schiff base derived from furfurylamine

摘要

Two new mononuclear complexes of manganese(III) viz. [MnL2(LH)2]ClO4 (1) and [MnL2(N3)]0.5CH3OH (2) have been synthesized by reacting manganese perchlorate with furfurylamine and salicylaldehyde (plus sodium azide in 2) where L = (2-hydroxybenzyl-2-furylmethyl)imine, an asymmetric bidentate Schiff base formed in situ to bind the Mn(III) ion. The complexes have been characterized by elementalanalysis, IR spectroscopy, TGA and single crystal X-ray diffraction studies. Structural studies reveal that the complexes 1 and 2 adopt an octahedral and a square pyramidal geometry, respectively. The antibacterial activity of the complexes has been tested against Gram(+) and Gram() bacteria.
