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.

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. There are four shorter (3.23 Å) and two longer (3.25 Å) La(1)-Rh(1) bond lengths. There are four shorter (3.21 Å) and two longer (3.29 Å) La(1)-As(1) bond lengths. Rh(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent As(1) atoms. There are two shorter (2.46 Å) and one longer (2.47 Å) Rh(1)-As(1) bond length. As(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Rh(1) atoms.
