Abstract

Reactions of 1-amidino-O-methylurea with cobaltous chloride in presence of water and liquor ammonia resulted in the formation of diammine bis(1-amidino-O-methylurea) cobalt(III) chloride. The present work describes the result of our investigations on the synthesis and characterization of mixed ligand complexes of 1-amidino-O-methylurea with some amino acids. Reactions of [Co(NH(AMU)]Cl2.2.5H2O with amino acids viz. L-valine, DL-alanine and glycyl-glycine in equimolar ratio, in water, resulted in the formation of [Co(val)(AMUH)]Cl2.2H2O, [Co(ala)(AMUH)]Cl.2.5H2O and [Co(gly-gly)(AMUH)]Cl2.H2O respectively. These complexes have been characterized by elemental analysis and molar conductance values. Octahedral structure has been proposed on the basis of IR , magnetic moment and electronic spectra of the complexes.
