Abstract

Abstract : The formation of binary complexes of Cr(III) and Fe(III) with a tripodal ligand cis, cis -1, 3, 5-tris(methylamino)cyclohexane ( tmach ) (L) has been investigated in solution. The overall stability constants of tmach with Cr(III) and Fe(III) were determined by potentiometric method at an ionic strength of 0.1 M NaClO4 at 25±1°C in aqueous medium. The formation of species like MLH2 5+, MLH 4+, ML 3+, ML(OH) 2+ and ML(OH)3 were observed. Fe(III) was found to form more stable complexes than Cr(III). Molecular mechanics calculations were performed to explain the mode of coordination in solution.
