Silanes refers to diverse kinds of charge-neutral silicon compounds with the formula SiR4. The R substituents can any combination of organic[1] or inorganic groups.[2] Most silanes contain Si-C bonds, and are discussed under organosilicon compounds.


By tradition, compounds with Si-O-Si bonds are usually not referred to as silanes. Instead, they are called siloxanes. One example is hexamethyldisiloxane, (CH3)3Si)2O.
