Materials Data on Sr3Ca by Materials Project

Abstract

Sr3Ca is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sr is bonded to eight equivalent Sr and four equivalent Ca atoms to form SrSr8Ca4 cuboctahedra that share corners with twelve equivalent SrSr8Ca4 cuboctahedra, edges with eight equivalent CaSr12 cuboctahedra, edges with sixteen equivalent SrSr8Ca4 cuboctahedra, faces with four equivalent CaSr12 cuboctahedra, and faces with fourteen equivalent SrSr8Ca4 cuboctahedra. All Sr–Sr bond lengths are 4.16 Å. All Sr–Ca bond lengths are 4.16 Å. Ca is bonded to twelve equivalent Sr atoms to form CaSr12 cuboctahedra that share corners with twelve equivalent CaSr12 cuboctahedra, edges with twenty-four equivalent SrSr8Ca4 cuboctahedra, faces with six equivalent CaSr12 cuboctahedra, and faces with twelve equivalent SrSr8Ca4 cuboctahedra.
