Tetrakis(trimethylsilyl)methane (TTMSM) is an organic compound with formula C₁₃H₃₆Si₄, consisting of four trimethylsilyl (Si(CH₃)₃) groups bonded to a central carbon atom. It is extremely sterically crowded but unlike with the all-carbon equivalent tetra-tert-butylmethane which is only known as a theoretical compound, the longer silicon-carbon bonds allow this compound to be synthesised.^[1][2][3][4]
