Synthesis of Mn(II) and Fe(II) Complexes with Ethylenediamine and Acetylacetonate Ligands

Abstract

Synthesis of acetylacetonato, ethylenediamine manganese (II) complex and acetylacetonato, ethylenediamine iron (II) complex were carried out, a pale yellow and brown solids were obtained from the reaction.  The solubility tests of the complexes were carried out, in which manganese (II) complex was found to be soluble in water, methanol and ethanol and insoluble in chloroform and petroleum ether while the iron (II) complex was found to be slightly soluble in water, methanol and ethanol and insoluble in chloroform and petroleum ether. The UV visible spectra of manganese (II) complex showed absorption maximum at around 480nm, and infrared spectra of manganese (II) complex showed absorption band at 1725cm^-1.

Keywords: Acetylacetone, manganese, iron, ethylenediamine.
