Materials Data on MnCoSb by Materials Project

Abstract

CoMnSb is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mn2+ is bonded to four equivalent Sb3- atoms to form MnSb4 tetrahedra that share corners with four equivalent CoSb4 tetrahedra, corners with twelve equivalent MnSb4 tetrahedra, and edges with six equivalent CoSb4 tetrahedra. All Mn–Sb bond lengths are 2.59 Å. Co1+ is bonded to four equivalent Sb3- atoms to form CoSb4 tetrahedra that share corners with four equivalent MnSb4 tetrahedra, corners with twelve equivalent CoSb4 tetrahedra, and edges with six equivalent MnSb4 tetrahedra. All Co–Sb bond lengths are 2.59 Å. Sb3- is bonded in a body-centered cubic geometry to four equivalent Mn2+ and four equivalent Co1+ atoms.
