FARIAS, Robson Fernandes de. Synthesis and characterization of manganese-glycine and copper-glycine adducts. Quím. Nova [online]. 2002, vol.25, n.5, pp.729-730. ISSN 0100-4042.

This work reports the synthesis and characterization of adducts of general formula MCl2.ngly, where M= Mn and Cu; n= 2 and 4, and gly= glycine. The manganese adducts were synthesized by dissolution of both, manganese chloride and glycine in water, whereas the copper adducts were obtained by using an alternative solid state synthesis approach. For all adducts, the obtained infrared data shows that the coordination involves the amine nitrogen atom, as well as an oxygen atom of the COO- group. The TG curves for the synthesized adducts exhibit only one mass loss step associated with the release of glycine molecules.

Keywords : glycine; copper; manganese; adducts.
