A Base‐Stabilized Ge–S Double Bond

The GeS bond in 1 is only 2.06 Å long, ca. 0.2 Å less than would be expected for a GeS single bond. The monomeric form of 1 is apparently stabilized by an intramolecular NGe donor bond, which in solution at higher temperatures is fluxional on the NMR time scale. The analogous oxygen compound 2 is dimeric. Compounds 1 and 2 were prepared in 98 and 60 % yield, respectively, starting with germanediyl 3 and either S8 or O2.
