The material described by LuIrSi crystallizes in the orthorhombic Pnma space group. Lu(1) is bonded in a 11-coordinate geometry to six equivalent Ir(1) and five equivalent Si(1) atoms. Ir(1) is bonded in a 10-coordinate geometry to six equivalent Lu(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to five equivalent Lu(1) and four equivalent Ir(1) atoms. is represented by the CIF card [CIF]
