摘要

[M (diphosphine) 2] 2+ complexes (where M= Ni and Pt) react with hydrogen in the presence of bases to form the corresponding hydrides,[HM (diphosphine) 2]+. In seven cases, equilibria have been observed from which the hydride donor ability (Δ G° H-) of the hydrides can be calculated. For six of these complexes, the Δ G° H-values calculated using heterolytic activation of hydrogen are compared with those based on thermodynamic cycles using p ...
