TbCuSi is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. Tb(1) is bonded to six equivalent Cu(1) and six equivalent Si(1) atoms to form a mixture of edge and face-sharing TbCu6Si6 cuboctahedra. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Cu(1) atoms.
