The compound described by Rh3In is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to eight Rh(1,1) and four equivalent In(1) atoms to form distorted RhIn4Rh8 cuboctahedra that share corners with four equivalent In(1)Rh12 cuboctahedra; corners with fourteen Rh(1,1)In4Rh8 cuboctahedra; edges with six equivalent In(1)Rh12 cuboctahedra; edges with twelve Rh(1,1)In4Rh8 cuboctahedra; faces with four equivalent In(1)Rh12 cuboctahedra; and faces with sixteen Rh(1,1)In4Rh8 cuboctahedra. In the second Rh site, Rh(1) is bonded to eight Rh(1,1) and four equivalent In(1) atoms to form distorted RhIn4Rh8 cuboctahedra that share corners with four equivalent In(1)Rh12 cuboctahedra; corners with fourteen Rh(1,1)In4Rh8 cuboctahedra; edges with six equivalent In(1)Rh12 cuboctahedra; edges with twelve Rh(1,1)In4Rh8 cuboctahedra; faces with four equivalent In(1)Rh12 cuboctahedra; and faces with sixteen Rh(1,1)In4Rh8 cuboctahedra.
