Sr3As crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded in a 4-coordinate geometry to four equivalent As(1) atoms. As(1) is bonded to twelve equivalent Sr(1) atoms to form a mixture of face and corner-sharing AsSr12 cuboctahedra.
Sr3As crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded in a 4-coordinate geometry to four equivalent As(1) atoms. There are two shorter (3.56 Å) and two longer (3.78 Å) Sr(1)-As(1) bond lengths. As(1) is bonded to twelve equivalent Sr(1) atoms to form a mixture of face and corner-sharing AsSr12 cuboctahedra.
