Materials Data on MnSbRh by Materials Project

Abstract

MnRhSb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mn is bonded in a body-centered cubic geometry to four equivalent Rh and four equivalent Sb atoms. All Mn–Rh bond lengths are 2.61 Å. All Mn–Sb bond lengths are 2.61 Å. Rh is bonded to four equivalent Mn and six equivalent Sb atoms to form distorted RhMn4Sb6 tetrahedra that share corners with four equivalent SbMn4Rh6 tetrahedra, corners with six equivalent RhMn4Sb6 tetrahedra, edges with six equivalent SbMn4Rh6 tetrahedra, and faces with twelve equivalent RhMn4Sb6 tetrahedra. All Rh–Sb bond lengths are 3.01 Å. Sb is bonded to four equivalent Mn and six equivalent Rh atoms to form distorted SbMn4Rh6 tetrahedra that share corners with four equivalent RhMn4Sb6 tetrahedra, corners with six equivalent SbMn4Rh6 tetrahedra, edges with six equivalent RhMn4Sb6 tetrahedra, and faces with twelve equivalent SbMn4Rh6 tetrahedra.
