Aurosilane Explained

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]
