Rh2CoSn is Heusler structured and crystallizes in the tetragonal I4/mmm space group. Rh(1) is bonded in a distorted body-centered cubic geometry to four equivalent Co(1) and four equivalent Sn(1) atoms. Co(1) is bonded to eight equivalent Rh(1) and four equivalent Sn(1) atoms to form distorted CoSn4Rh8 cuboctahedra that share corners with four equivalent Co(1)Sn4Rh8 cuboctahedra, corners with eight equivalent Sn(1)Co4Rh8 cuboctahedra, edges with eight equivalent Co(1)Sn4Rh8 cuboctahedra, faces with four equivalent Co(1)Sn4Rh8 cuboctahedra, and faces with six equivalent Sn(1)Co4Rh8 cuboctahedra. Sn(1) is bonded to eight equivalent Rh(1) and four equivalent Co(1) atoms to form distorted SnCo4Rh8 cuboctahedra that share corners with four equivalent Sn(1)Co4Rh8 cuboctahedra, corners with eight equivalent Co(1)Sn4Rh8 cuboctahedra, edges with eight equivalent Sn(1)Co4Rh8 cuboctahedra, faces with four equivalent Sn(1)Co4Rh8 cuboctahedra, and faces with six equivalent Co(1)Sn4Rh8 cuboctahedra.
