The synthesis of the monomeric organogermanium(II) hydrides [(LGeH)M(CO) 5 ] [M = Cr ( 4 ), W ( 5 )] by utilizing the C , N ‐chelating ligand L {L = [2‐(CH 2 NEt 2 )‐4,6‐ t Bu 2 C 6 H 2 ] – } was explored. Stabilization of the Ge H terminal bond in 4 and 5 was accompanied by a combination of electronic and steric protection of ligand L. The reactivity of the Ge H terminal bond was also investigated, and attempts to reduce the polar C≡N bond in t BuNC provided an unexpected N–C bond‐cleavage reaction yielding organogermanium(II) cyanides [(LGeCN)M(CO) 5 ] [M = Cr ( 6 ), W ( 7 )] instead of a hydrogermylation reaction.
