HOMO AND HETEROTRINUCLEAR IRON ACETATES: AN EXPERIMENT FOR THE COORDINATION CHEMISTRY LABORATORY. Homo and heterotrinuclear acetates are unique compounds having mu(3)-oxo bridge and many interesting properties of such compounds are derived from this structure. Some undergraduate inorganic textbooks discuss several aspects of these compounds and we present here an undergraduate experiment for the high-yield synthesis of [Fe(2)MO(CH(3)CO(2))(6)(H(2)O)(3)], with M = Fe(3+), Co(2+) and Ni(2+), as well as their characterization using infrared spectroscopy and cyclic voltametry. The proposed experiment gives the opportunity to discuss several concepts of coordination chemistry that follow the characterization techniques, such as: types of acetate coordination, reversibility of electrochemical processes, quelate and trans effects and lability.33818151820
