RhAsSe is Spinel-like structured and crystallizes in the cubic P2_13 space group. Rh(1) is bonded to three equivalent As(1) and three equivalent Se(1) atoms to form RhAs3Se3 octahedra that share corners with twelve equivalent Rh(1)As3Se3 octahedra, corners with three equivalent As(1)Rh3Se tetrahedra, and corners with three equivalent Se(1)AsRh3 tetrahedra. The corner-sharing octahedral tilt angles are 64°. As(1) is bonded to three equivalent Rh(1) and one Se(1) atom to form distorted AsRh3Se tetrahedra that share corners with three equivalent Rh(1)As3Se3 octahedra, corners with six equivalent As(1)Rh3Se tetrahedra, and corners with nine equivalent Se(1)AsRh3 tetrahedra. The corner-sharing octahedral tilt angles are 78°. Se(1) is bonded to three equivalent Rh(1) and one As(1) atom to form SeAsRh3 tetrahedra that share corners with three equivalent Rh(1)As3Se3 octahedra, corners with six equivalent Se(1)AsRh3 tetrahedra, and corners with nine equivalent As(1)Rh3Se tetrahedra. The corner-sharing octahedral tilt angles are 79°.
