The structure described by 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 sites. In the first Au site, Au(2) is bonded in a trigonal non-coplanar geometry to three equivalent Si(1) atoms. In the second Au site, Au(1) is bonded in a distorted single-bond geometry to one Si(1) atom. In the third Au site, Au(3) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Si(1) atoms. Si(1) is bonded in a 6-coordinate geometry to two equivalent Au(1), two equivalent Au(2), and two equivalent Au(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
