SrTl3 crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded to twelve equivalent Tl(1) atoms to form a mixture of corner and face-sharing SrTl12 cuboctahedra. Tl(1) is bonded in a 10-coordinate geometry to four equivalent Sr(1) and six equivalent Tl(1) atoms.
SrTl3 crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded to twelve equivalent Tl(1) atoms to form a mixture of corner and face-sharing SrTl12 cuboctahedra. There are six shorter (3.51 Å) and six longer (3.58 Å) Sr(1)-Tl(1) bond lengths. Tl(1) is bonded in a 10-coordinate geometry to four equivalent Sr(1) and six equivalent Tl(1) atoms. All Tl(1)-Tl(1) bond lengths are 3.37 Å.
