The material described by YbAuSi crystallizes in the orthorhombic Imm2 space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 12-coordinate geometry to six equivalent Au(1) and six equivalent Si(1) atoms. In the second Yb site, Yb(2) is bonded in a 12-coordinate geometry to six equivalent Au(1) and six equivalent Si(1) atoms. Au(1) is bonded in a 10-coordinate geometry to three equivalent Yb(1), three equivalent Yb(2), one Au(1), and three equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to three equivalent Yb(1), three equivalent Yb(2), three equivalent Au(1), and one Si(1) atom. is represented by the CIF card [CIF]
