Materials Data on SrCa by Materials Project

Abstract

SrCa crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Sr is bonded to six equivalent Sr and six equivalent Ca atoms to form SrSr6Ca6 cuboctahedra that share corners with eighteen equivalent SrSr6Ca6 cuboctahedra, edges with six equivalent SrSr6Ca6 cuboctahedra, edges with twelve equivalent CaSr6Ca6 cuboctahedra, faces with eight equivalent SrSr6Ca6 cuboctahedra, and faces with twelve equivalent CaSr6Ca6 cuboctahedra. All Sr–Sr bond lengths are 4.12 Å. All Sr–Ca bond lengths are 4.06 Å. Ca is bonded to six equivalent Sr and six equivalent Ca atoms to form CaSr6Ca6 cuboctahedra that share corners with eighteen equivalent CaSr6Ca6 cuboctahedra, edges with six equivalent CaSr6Ca6 cuboctahedra, edges with twelve equivalent SrSr6Ca6 cuboctahedra, faces with eight equivalent CaSr6Ca6 cuboctahedra, and faces with twelve equivalent SrSr6Ca6 cuboctahedra. All Ca–Ca bond lengths are 4.12 Å.
