Understanding the Chelate Effect Through Descriptive Chemistry and Spectroscopy
Faculty Mentor(s) Name(s)
Dr. Peter Rosado-Flores
Abstract
Amines are very resourceful as electron pair donors due to the lone pair on their nitrogen’s which allows for them to form coordinate bonds with a central transition metal ion. Transition metal amine complexes have found uses in both medicine and chemical synthesis in the form of anti-cancer drugs such as cisplatin and reagents like Reinecke’s salt. Through the chelate effect, these amines can be displaced in favor of molecules with multiple binding sites; bidentate or polydentate ligands such as ethylenediamine or EDTA for example. The goals of this research were to synthesize amine complexes of various transition metals, observe the chelate effect initiated by ethylenediamine and acetylacetone, and characterize each amine and chelate complex with the equipment available. Complexes of iron (II), iron (III), nickel (II), and cobalt (II) were successfully synthesized from their metal sulfate or metal acetate form. Each was analyzed by means of IR and UV-Vis.
