The current project pursues the discovery of novel low-melting ionic compounds involving closo- and nido- carborane cluster anions. These materials are of interest for their potentially valuable electrochemical properties. Thermodynamic studies of the phase transition processes in these materials are focused on the relative enthalpy and entropy contributions as a function of varied anion and cation structure as well as melting point trends. (Cations include substituted imidazolium and pyridinium species). The compounds - such as 1-Butyl-2,3-dimethylimidazolium [nido-C2B9H12] (structure shown below) - are synthesized in the metathesis reactions and studied by Differential Scanning Calorimetry and X-ray single crystal diffraction methods.
