Trimethylstibine

Trimethylstibine is an organoantimony compound with the formula Sb(CH₃)₃. It is a colorless pyrophoric and toxic liquid.^[2] It is synthesized by treatment of antimony trichloride and methyl Grignard reagent.^[3] It is produced by anaerobic bacteria in antimony-rich soils.^[4] In contrast to trimethylphosphine, trimethylstibine is a weaker Lewis base. It is used in the production of some III-V semiconductors.
