Materials Data on InPt3 by Materials Project

Abstract

Pt3In 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 In2+ atoms to form distorted PtIn4Pt8 cuboctahedra that share corners with twelve equivalent PtIn4Pt8 cuboctahedra, edges with eight equivalent InPt12 cuboctahedra, edges with sixteen equivalent PtIn4Pt8 cuboctahedra, faces with four equivalent InPt12 cuboctahedra, and faces with fourteen equivalent PtIn4Pt8 cuboctahedra. All Pt–Pt bond lengths are 2.87 Å. All Pt–In bond lengths are 2.87 Å. In2+ is bonded to twelve equivalent Pt+0.67- atoms to form InPt12 cuboctahedra that share corners with twelve equivalent InPt12 cuboctahedra, edges with twenty-four equivalent PtIn4Pt8 cuboctahedra, faces with six equivalent InPt12 cuboctahedra, and faces with twelve equivalent PtIn4Pt8 cuboctahedra.
