Materials Data on AgPt3 by Materials Project

Abstract

Pt3Ag is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pt+0.67- is bonded to eight equivalent Pt+0.67- and four equivalent Ag2+ atoms to form PtAg4Pt8 cuboctahedra that share corners with twelve equivalent PtAg4Pt8 cuboctahedra, edges with eight equivalent AgPt12 cuboctahedra, edges with sixteen equivalent PtAg4Pt8 cuboctahedra, faces with four equivalent AgPt12 cuboctahedra, and faces with fourteen equivalent PtAg4Pt8 cuboctahedra. All Pt–Pt bond lengths are 2.83 Å. All Pt–Ag bond lengths are 2.83 Å. Ag2+ is bonded to twelve equivalent Pt+0.67- atoms to form AgPt12 cuboctahedra that share corners with twelve equivalent AgPt12 cuboctahedra, edges with twenty-four equivalent PtAg4Pt8 cuboctahedra, faces with six equivalent AgPt12 cuboctahedra, and faces with twelve equivalent PtAg4Pt8 cuboctahedra.
