Materials Data on CoPt3 by Materials Project

Abstract

Pt3Co is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Co2+ is bonded to twelve equivalent Pt+0.67- atoms to form CoPt12 cuboctahedra that share corners with twelve equivalent CoPt12 cuboctahedra, edges with twenty-four equivalent PtCo4Pt8 cuboctahedra, faces with six equivalent CoPt12 cuboctahedra, and faces with twelve equivalent PtCo4Pt8 cuboctahedra. All Co–Pt bond lengths are 2.75 Å. Pt+0.67- is bonded to four equivalent Co2+ and eight equivalent Pt+0.67- atoms to form distorted PtCo4Pt8 cuboctahedra that share corners with twelve equivalent PtCo4Pt8 cuboctahedra, edges with eight equivalent CoPt12 cuboctahedra, edges with sixteen equivalent PtCo4Pt8 cuboctahedra, faces with four equivalent CoPt12 cuboctahedra, and faces with fourteen equivalent PtCo4Pt8 cuboctahedra. All Pt–Pt bond lengths are 2.75 Å.
