Materials Data on SrCa3 by Materials Project

Abstract

SrCa3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sr is bonded to twelve equivalent Ca atoms to form SrCa12 cuboctahedra that share corners with twelve equivalent SrCa12 cuboctahedra, edges with twenty-four equivalent CaSr4Ca8 cuboctahedra, faces with six equivalent SrCa12 cuboctahedra, and faces with twelve equivalent CaSr4Ca8 cuboctahedra. All Sr–Ca bond lengths are 3.98 Å. Ca is bonded to four equivalent Sr and eight equivalent Ca atoms to form CaSr4Ca8 cuboctahedra that share corners with twelve equivalent CaSr4Ca8 cuboctahedra, edges with eight equivalent SrCa12 cuboctahedra, edges with sixteen equivalent CaSr4Ca8 cuboctahedra, faces with four equivalent SrCa12 cuboctahedra, and faces with fourteen equivalent CaSr4Ca8 cuboctahedra. All Ca–Ca bond lengths are 3.98 Å.
