The material structure described by LuSi crystallizes in the orthorhombic Cmcm space group. Lu(1) is bonded in a 7-coordinate geometry to seven equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to seven equivalent Lu(1) and two equivalent Si(1) atoms. is represented by the CIF file [CIF]
