LuSi2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. Lu(1) is bonded to twelve equivalent Si(1) atoms to form a mixture of edge and face-sharing LuSi12 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to six equivalent Lu(1) and three equivalent Si(1) atoms.
