Materials Data on FePt3 by Materials Project

Abstract

FePt3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Fe2+ is bonded to twelve equivalent Pt+0.67- atoms to form FePt12 cuboctahedra that share corners with twelve equivalent FePt12 cuboctahedra, edges with twenty-four equivalent PtFe4Pt8 cuboctahedra, faces with six equivalent FePt12 cuboctahedra, and faces with twelve equivalent PtFe4Pt8 cuboctahedra. All Fe–Pt bond lengths are 2.74 Å. Pt+0.67- is bonded to four equivalent Fe2+ and eight equivalent Pt+0.67- atoms to form distorted PtFe4Pt8 cuboctahedra that share corners with twelve equivalent PtFe4Pt8 cuboctahedra, edges with eight equivalent FePt12 cuboctahedra, edges with sixteen equivalent PtFe4Pt8 cuboctahedra, faces with four equivalent FePt12 cuboctahedra, and faces with fourteen equivalent PtFe4Pt8 cuboctahedra. All Pt–Pt bond lengths are 2.74 Å.
