The material described by Rh2FeSn is Heusler structured and crystallizes in the tetragonal I4/mmm space group. Fe(1) is bonded to eight equivalent Rh(1) and four equivalent Sn(1) atoms to form distorted FeSn4Rh8 cuboctahedra that share corners with four equivalent Fe(1)Sn4Rh8 cuboctahedra, corners with eight equivalent Sn(1)Fe4Rh8 cuboctahedra, edges with eight equivalent Fe(1)Sn4Rh8 cuboctahedra, faces with four equivalent Fe(1)Sn4Rh8 cuboctahedra, and faces with six equivalent Sn(1)Fe4Rh8 cuboctahedra. Rh(1) is bonded in a distorted body-centered cubic geometry to four equivalent Fe(1) and four equivalent Sn(1) atoms. Sn(1) is bonded to four equivalent Fe(1) and eight equivalent Rh(1) atoms to form distorted SnFe4Rh8 cuboctahedra that share corners with four equivalent Sn(1)Fe4Rh8 cuboctahedra, corners with eight equivalent Fe(1)Sn4Rh8 cuboctahedra, edges with eight equivalent Sn(1)Fe4Rh8 cuboctahedra, faces with four equivalent Sn(1)Fe4Rh8 cuboctahedra, and faces with six equivalent Fe(1)Sn4Rh8 cuboctahedra. is represented by the CIF file [CIF]
