In general, it is assumed that the reaction between silanes and late transition metal fragments yields silyl hydride species as oxidative addition products. However, the silane complex Ni(iPr2Im)2(SiHMePh2) (iPr2Im = 1, 3‐diisopropylimidazolin‐2‐ylidene) (3a), might represent one of the rare systems where a stable η2‐(Si–H)Ni intermediate of the oxidative addition process has been isolated. Indeed,3ais characterized by an acute [ang]Si–Ni–H angle of 62.0(2)°, a rather short Si–H bond length of 1.992(6) Å and displays a silicon‐hydride cross peak in Si‐H‐HMQC 2D‐NMR studies. We therefore selected the latter system for a combined experimental and theoretical charge density study to explore the electronic prerequisites which hinder the full completion of the oxidative addition step in transition metal silane complexes and cause the presence of remanent Si–H interactions in these species.
