Free energies of cation-molecule complex formation and of cation-solvent transfers (ref. 1)

Abstract

The effects of molecular structure on gas phase basicity toward Li+ has been extensively studied. It is shown that both the magnitudes and the basicity orders differ markedly from the corresponding gas phase bacisities toward H+. An analysis of these results is presented together with some preliminary comparisons of basicity orders observed in other adducts having largely electrostatic bonds, i.e., for Al+, K+, Mn+, and neutral hydrogen-bond donors. Implications to ionic solvation energies of the differing basicity orders are considered. © 1990 De Gruyter
