| Abstract: | Complex formation between 15-crown-5 and malononitrile was studied in twelve solvents by calorimetry. Thermodynamic parameters for the crown ether adduct were determined and used in a LFER analysis to ascertain the solvent effects on the complexation process. Enthalpy of solution data show that malononitrile is solvated by electron pair donation by the solvents and the crown ether is solvated by donating electron pairs to the solvents. The complex is more solvated than the monomers. |
