Study of Bioinorganic Ternary Complexes of Mn (II) with Antibiotics & Aspirin by Polarographic Technique

Abstract

Polarography was used to determine the stability constants (log b) of mixed ligand bioinorganic complexes of Mn (II) with some antibiotics as primary ligands and aspirin as secondary ligand at pH=7.30 ± 0.01 and ionic strength m=1.0 M NaClO4 at 298 K. The waves of Mn and its complexes were quasireversible. Mn (II) formed 1:1:1, 1:2:1 and 1:1:2 complexes. Stability of these complexes is explain on the basis of sizes and basic nature of these Ligands.
