Sr Sr Tl Ga
Sr2TlGa crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Sr2TlGa cluster. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Tl(1) atom. The Sr(1)-Tl(1) bond length is 1.81 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Ga(1) atom. The Sr(2)-Ga(1) bond length is 1.76 Å. Tl(1) is bonded in a distorted water-like geometry to one Sr(1) and one Ga(1) atom. The Tl(1)-Ga(1) bond length is 1.88 Å. Ga(1) is bonded in a distorted water-like geometry to one Sr(2) and one Tl(1) atom.
