Trimethylgallium
Chemical compound / From Wikipedia, the free encyclopedia
Trimethylgallium, often abbreviated to TMG or TMGa, is the organogallium compound with the formula Ga(CH3)3. It is a colorless, pyrophoric liquid.[1] Unlike trimethylaluminium, TMG adopts a monomeric structure.[2] When examined in detail, the monomeric units are clearly linked by multiple weak Ga---C interactions, reminiscent of the situation for trimethylindium.[3]
