SrWTl2 crystallizes in the triclinic P1 space group. Sr(1) is bonded in a distorted single-bond geometry to one W(1) and two equivalent Tl(2) atoms. The Sr(1)-W(1) bond length is 1.65 Å. There is one shorter (2.59 Å) and one longer (2.89 Å) Sr(1)-Tl(2) bond length. W(1) is bonded in a distorted single-bond geometry to one Sr(1), two equivalent Tl(1), and two equivalent Tl(2) atoms. There is one shorter (2.59 Å) and one longer (2.89 Å) W(1)-Tl(1) bond length. There is one shorter (3.40 Å) and one longer (3.63 Å) W(1)-Tl(2) bond length. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 3-coordinate geometry to two equivalent W(1) and one Tl(2) atom. The Tl(1)-Tl(2) bond length is 2.05 Å. In the second Tl site, Tl(2) is bonded in a 7-coordinate geometry to two equivalent Sr(1), two equivalent W(1), one Tl(1), and two equivalent Tl(2) atoms. Both Tl(2)-Tl(2) bond lengths are 3.16 Å.
