The material described by Lu3Si is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Lu(1) is bonded to eight equivalent Lu(1) and four equivalent Si(1) atoms to form distorted LuLu8Si4 cuboctahedra that share corners with twelve equivalent Lu(1)Lu8Si4 cuboctahedra, edges with eight equivalent Si(1)Lu12 cuboctahedra, edges with sixteen equivalent Lu(1)Lu8Si4 cuboctahedra, faces with four equivalent Si(1)Lu12 cuboctahedra, and faces with fourteen equivalent Lu(1)Lu8Si4 cuboctahedra. Si(1) is bonded to twelve equivalent Lu(1) atoms to form SiLu12 cuboctahedra that share corners with twelve equivalent Si(1)Lu12 cuboctahedra, edges with twenty-four equivalent Lu(1)Lu8Si4 cuboctahedra, faces with six equivalent Si(1)Lu12 cuboctahedra, and faces with twelve equivalent Lu(1)Lu8Si4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
