SrCa is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Sr(1) is bonded to six equivalent Sr(1) and six equivalent Ca(1) atoms to form SrSr6Ca6 cuboctahedra that share corners with eighteen equivalent Sr(1)Sr6Ca6 cuboctahedra, edges with six equivalent Sr(1)Sr6Ca6 cuboctahedra, edges with twelve equivalent Ca(1)Sr6Ca6 cuboctahedra, faces with eight equivalent Sr(1)Sr6Ca6 cuboctahedra, and faces with twelve equivalent Ca(1)Sr6Ca6 cuboctahedra. Ca(1) is bonded to six equivalent Sr(1) and six equivalent Ca(1) atoms to form CaSr6Ca6 cuboctahedra that share corners with eighteen equivalent Ca(1)Sr6Ca6 cuboctahedra, edges with six equivalent Ca(1)Sr6Ca6 cuboctahedra, edges with twelve equivalent Sr(1)Sr6Ca6 cuboctahedra, faces with eight equivalent Ca(1)Sr6Ca6 cuboctahedra, and faces with twelve equivalent Sr(1)Sr6Ca6 cuboctahedra.
