N1 - Funding Information: We thank the Russian Science Foundation for the financial support of experiments with parahydrogen (project 20‐62‐47038; A.S.K., A.V.Y. and K.L.I.) and VT NMR measurements (project 20‐63‐47107; N.V.K. and A.A.P.). E.I.M. and A.A.K. are grateful for the state financial support for FRC Kazan Scientific Center of the RAS. The support of the Ministry of Science and Higher Education of the Russian Federation for providing access to NMR facilities at ITC SB RAS and CMCS of INEOS RAS is greatly appreciated.

N2 - 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.
