Abstract

Density functional theory and the polarizable continuum solvation model have been applied to compute thermodynamic hydride donor abilities of cationic [MH(diphosphine)2]+ complexes (M = Ni, Pd, Pt). The accuracy of the applied computational methods has been assessed by comparison of calculated Gibbs-free energies of reactions involving the hydrides as products with available experimental data. The mean absolute deviation of the calculated results from experiment varies between 2 and 5 kcal/mol depending on the choice of the solute cavity model. The PCM-UA0 method, which was found to provide the most reliable predictions for the investigated reactions, was applied to estimate the hydricity of [MH(diphosphine)2]+ complexes. The recently synthesized [PdH(dppe)2]+ cation is predicted to be an effective hydride donor.
