The crystal structure described by LaRhAs is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. La(1) is bonded to six equivalent Rh(1) and six equivalent As(1) atoms to form a mixture of edge and face-sharing LaAs6Rh6 cuboctahedra. Rh(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Rh(1) atoms. is represented by the CIF file [CIF]
