1,3,5,7-Tetramethyl-1,3,5,7-tetrasilaadamantane is the organosilicon compound with the formula (CH
2)
6(SiCH
3)
4. It is a colorless solid that is soluble in organic solvents. The compound is one of the iconic carbosilanes, featuring alternating –Si–C–Si–C– linkages.[2] Otherwise it can be described as a diamondoid cluster. It arises as one of many products from the pyrolysis of tetramethylsilane. A more efficient route involves the reaction of the cyclic carbosilane (CH
2Si(CH
