The material structure described by 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. is represented by the CIF card [CIF]
