Materials Data on Si3Au10 by Materials Project
Au10Si3 is Tungsten structured and crystallizes in the cubic I-43m space group. The structure is zero-dimensional and consists of two Au10Si3 clusters. there are three inequivalent Au+0.40- sites. In the first Au+0.40- site, Au+0.40- is bonded in a trigonal non-coplanar geometry to three equivalent Si+1.33+ atoms. All Au–Si bond lengths are 2.58 Å. In the second Au+0.40- site, Au+0.40- is bonded in a distorted single-bond geometry to one Si+1.33+ atom. The Au–Si bond length is 2.54 Å. In the third Au+0.40- site, Au+0.40- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Si+1.33+ atoms. All Au–Si bond lengths are 2.62 Å. Si+1.33+ is bonded in a 8-coordinate geometry to six Au+0.40- atoms.
