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-(CH2NEt2)-4,6-tBu2C6H2]–} was explored. Stabilization of the GeH terminal bond in 4 and 5 was accompanied by a combination of electronic and steric protection of ligand L. The reactivity of the GeH terminal bond was also investigated, and attempts to reduce the polar C≡N bond in tBuNC 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.
