SrTl2 crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded in a 6-coordinate geometry to twelve equivalent Tl(1) atoms. Tl(1) is bonded in a 10-coordinate geometry to six equivalent Sr(1) and four equivalent Tl(1) atoms.
SrTl2 crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded in a 6-coordinate geometry to twelve equivalent Tl(1) atoms. There are six shorter (3.40 Å) and six longer (3.87 Å) Sr(1)-Tl(1) bond lengths. Tl(1) is bonded in a 10-coordinate geometry to six equivalent Sr(1) and four equivalent Tl(1) atoms. There are three shorter (3.07 Å) and one longer (3.36 Å) Tl(1)-Tl(1) bond length.
