In4GeSb2Te is Stannite structured and crystallizes in the tetragonal I-42m space group. In(1) is bonded to one Ge(1), two equivalent Sb(1), and one Te(1) atom to form corner-sharing InGeSb2Te tetrahedra. Ge(1) is bonded to four equivalent In(1) atoms to form GeIn4 tetrahedra that share corners with four equivalent Te(1)In4 tetrahedra and corners with eight equivalent Sb(1)In4 tetrahedra. Sb(1) is bonded to four equivalent In(1) atoms to form SbIn4 tetrahedra that share corners with four equivalent Ge(1)In4 tetrahedra, corners with four equivalent Sb(1)In4 tetrahedra, and corners with four equivalent Te(1)In4 tetrahedra. Te(1) is bonded to four equivalent In(1) atoms to form TeIn4 tetrahedra that share corners with four equivalent Ge(1)In4 tetrahedra and corners with eight equivalent Sb(1)In4 tetrahedra.
