• Resumen

  • Cyclic voltammetry experiments on [60]fullerene, (C60), and (dihapto-[60]fullerene) pentacarbonyl tungsten(0), (?2-C60)W(CO)5, constitute an educational experiment for the inorganic chemistry laboratory with a primary objective to teach the chemical interpretation of a voltammogram, in particular the relation between the frontier LUMOs of [60]fullerene and the number of reduction�oxidation waves of [60]fullerene and (dihapto-[60]fullerene)W(CO)5. The proposed experiments may be combined with the kinetics experiments on the ligand�exchange reactions on (?2-C60)W(CO)5, and with the sunlight-induced photosynthesis and characterization of (?2-C60)W(CO)5, published in this Journal, to complete a series of three experiments for the inorganic chemistry laboratory that promotes understanding and integration of the following inorganic chemistry concepts: activation parameters, bonding, electronic structure, kinetics, mechanisms, and thermodynamic bond enthalpy.
