Aurosilane is an inorganic compound with a chemical formula of SiAu4. In this compound, gold acts as an electron acceptor with a valence of –1. Aurosilane has been isolated as a type of gold silane.[1] Its unit cell parameters are a = 5.658, c = 5.605 A.[2] The LUMO and the four Si-Au bonding orbitals of SiAu4 are similar to those of SiH4.[3]
In addition, silicon can also form other compounds with gold such as Si3Au3.[4]
