Antifungal and Spectral Studies of Cr(III) and Mn(II) Complexes Derived from 3,3′-Thiodipropionic Acid Derivative

Abstract

The Cr(III) and Mn(II) complexes with a ligand derived from 3,3′-thiodipropionic acid have been synthesized and characterized by elemental analysis, molar conductance measurements, magnetic susceptibility measurements, IR, UV, and EPR spectral studies. The complexes are found to have [Cr(L)X]X2 and [Mn(L)X]X, compositions, where L = quinquedentate ligand and X=NO3−, Cl− and OAc−. The complexes possess the six coordinated octahedral geometry with monomeric compositions. The evaluated bonding parameters, Aiso and β, account for the covalent type metal-ligand bonding. The fungicidal activity of the compounds was evaluated in vitro by employing Food Poison Technique.
