RhBiS is Spinel-like structured and crystallizes in the cubic P2_13 space group. Rh(1) is bonded to three equivalent Bi(1) and three equivalent S(1) atoms to form RhBi3S3 octahedra that share corners with twelve equivalent Rh(1)Bi3S3 octahedra, corners with three equivalent Bi(1)Rh3S tetrahedra, and corners with three equivalent S(1)BiRh3 trigonal pyramids. The corner-sharing octahedral tilt angles are 63°. Bi(1) is bonded to three equivalent Rh(1) and one S(1) atom to form distorted BiRh3S tetrahedra that share corners with three equivalent Rh(1)Bi3S3 octahedra, corners with six equivalent Bi(1)Rh3S tetrahedra, and corners with nine equivalent S(1)BiRh3 trigonal pyramids. The corner-sharing octahedral tilt angles are 80°. S(1) is bonded to three equivalent Rh(1) and one Bi(1) atom to form SBiRh3 trigonal pyramids that share corners with three equivalent Rh(1)Bi3S3 octahedra, corners with nine equivalent Bi(1)Rh3S tetrahedra, and corners with six equivalent S(1)BiRh3 trigonal pyramids. The corner-sharing octahedral tilt angles are 79°.
