The material structure described by UPtSi crystallizes in the monoclinic C2/m space group. U(1) is bonded in a 12-coordinate geometry to six equivalent Pt(1) and six equivalent Si(1) atoms. Pt(1) is bonded in a 10-coordinate geometry to six equivalent U(1), one Pt(1), and three equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to six equivalent U(1), three equivalent Pt(1), and one Si(1) atom. is represented by the CIF file [CIF]
