Materials Data on CoSnRh2 by Materials Project

Abstract

Rh2CoSn is Heusler structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Rh is bonded in a distorted body-centered cubic geometry to four equivalent Co and four equivalent Sn atoms. All Rh–Co bond lengths are 2.72 Å. All Rh–Sn bond lengths are 2.72 Å. Co is bonded to eight equivalent Rh and four equivalent Sn atoms to form distorted CoSn4Rh8 cuboctahedra that share corners with four equivalent CoSn4Rh8 cuboctahedra, corners with eight equivalent SnCo4Rh8 cuboctahedra, edges with eight equivalent CoSn4Rh8 cuboctahedra, faces with four equivalent CoSn4Rh8 cuboctahedra, and faces with six equivalent SnCo4Rh8 cuboctahedra. All Co–Sn bond lengths are 2.89 Å. Sn is bonded to eight equivalent Rh and four equivalent Co atoms to form distorted SnCo4Rh8 cuboctahedra that share corners with four equivalent SnCo4Rh8 cuboctahedra, corners with eight equivalent CoSn4Rh8 cuboctahedra, edges with eight equivalent SnCo4Rh8 cuboctahedra, faces with four equivalent SnCo4Rh8 cuboctahedra, and faces with six equivalent CoSn4Rh8 cuboctahedra.
