Tetralithiomethane, also known as tetralithium carbide, is an organolithium compound with the formula CLi4. It is an extremely pyrophoric red solid and is the lithium analog of methane.[2]
Deuterated methane CD4 can also be produced by reacting heavy water with tetralithiomethane.
CLi4 + 4 D2O → CD4 + 4 LiOD
When tetralithiomethane is heated to 225 °C, it decomposes to lithium carbide and lithium metal.[1][2]
Due to the known affinity of lithium ions Li+ for hydrogen moleculesH2 and therefore potential applications in hydrogen storage materials, tetralithiomethane has been studied computationally for its aggregation, H2 affinity, and binding to various graphene-type surfaces.[4]
