ThGeSi is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. Th(1) is bonded to six equivalent Ge(1) and six equivalent Si(1) atoms to form a mixture of face and edge-sharing ThSi6Ge6 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Th(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to six equivalent Th(1) and three equivalent Ge(1) atoms.
