The interaction of a series of [Ni(PR12NR22)2]2+ complexes 1–4 (where PR12NR22=1,5-R2-3,7-R1-1,5-diaza-3,7-diphosphacyclooctane; R1=o-Py, Ph; R2=CHPh2, p-Tol) with H2 is reversible yielding the products of heterolytic splitting of dihydrogen in the metal coordination sphere - [NiH(PR12NR22)(PR12NR22H)]2+. Experiments conducted with parahydrogen allowed to see the signal at about −4 ppm corresponding to the metal-bound H2 in the nickel dihydrogen complex [Ni(η2−H2)(PPh2NCHPh22)2]2+ (3-H2) – the short-living non-classical intermediate, which so far has been revealed only computationally.
