Abstract

S.R. Kelode and P. R. Mandlik

Solid complexes involving Co(II), Cu(II), Zn(II) Cr(III) and Fe(III) ions and Schiff base derived from salicylaldehyde and 2,4-dimethylaniline have been synthesized by conventional method. All the complexes have been characterized by elemental analyses, magnetic moment, electronic and infrared spectra and thermogravimetric analysis. An analysis of TG curves of LH and its metal complexes show that the ligand decomposed in two stages while all the complexes decomposed in three stages. Thermal stability order of the complexes was obtained on the basis of their half decomposition temperature. All the compounds have been assessed by screening the compounds against E. coli,  S. abong, S. aureus, P. arugineosa, B. subtilis, A. niger and C. albicans.
