The crystal structure described by LuPt2Si is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Pnma space group. Lu(1) is bonded in a 11-coordinate geometry to eight equivalent Pt(1) and three equivalent Si(1) atoms. Pt(1) is bonded in a 7-coordinate geometry to four equivalent Lu(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to three equivalent Lu(1) and six equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
