TlSmS2O9 crystallizes in the monoclinic P2_1/c space group. The structure consists of four 7440-28-0 atoms inside a SmS2O9 framework. In the SmS2O9 framework, Sm(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), one O(4), one O(5), one O(6), one O(7), one O(8), and one O(9) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a tetrahedral geometry to one O(2), one O(6), one O(7), and one O(8) atom. In the second S site, S(2) is bonded in a tetrahedral geometry to one O(1), one O(3), one O(4), and one O(9) atom. There are nine inequivalent O sites. In the first O site, O(5) is bonded in a single-bond geometry to one Sm(1) atom. In the second O site, O(6) is bonded in a distorted water-like geometry to one Sm(1) and one S(1) atom. In the third O site, O(7) is bonded in a distorted water-like geometry to one Sm(1) and one S(1) atom. In the fourth O site, O(8) is bonded in a distorted bent 150 degrees geometry to one Sm(1) and one S(1) atom. In the fifth O site, O(1) is bonded in a single-bond geometry to one S(2) atom. In the sixth O site, O(9) is bonded in a distorted bent 150 degrees geometry to one Sm(1) and one S(2) atom. In the seventh O site, O(2) is bonded in a bent 150 degrees geometry to one Sm(1) and one S(1) atom. In the eighth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Sm(1) and one S(2) atom. In the ninth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Sm(1) and one S(2) atom.
