The structure described by UAuSi crystallizes in the monoclinic C2/m space group. U(1) is bonded in a 11-coordinate geometry to six equivalent Au(1) and five equivalent Si(1) atoms. Au(1) is bonded in a 10-coordinate geometry to six equivalent U(1), one Au(1), and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to five equivalent U(1), three equivalent Au(1), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
