Sr is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to six equivalent Sr(1) and six equivalent Sr(2) atoms to form a mixture of face, corner, and edge-sharing SrSr12 cuboctahedra. In the second Sr site, Sr(2) is bonded to six equivalent Sr(1) and six equivalent Sr(2) atoms to form a mixture of face, corner, and edge-sharing SrSr12 cuboctahedra.

In the first Sr site, Sr(1) is bonded to six equivalent Sr(1) and six equivalent Sr(2) atoms to form a mixture of face, corner, and edge-sharing SrSr12 cuboctahedra. All Sr(1)-Sr(1) bond lengths are 4.30 Å. All Sr(1)-Sr(2) bond lengths are 4.33 Å. In the second Sr site, Sr(2) is bonded to six equivalent Sr(1) and six equivalent Sr(2) atoms to form a mixture of face, corner, and edge-sharing SrSr12 cuboctahedra. All Sr(2)-Sr(2) bond lengths are 4.30 Å.
