The material described by As2S2O9 is Indium-like structured and crystallizes in the monoclinic Pc space group. The structure is zero-dimensional and consists of four As2S2O9 clusters. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted T-shaped geometry to one O(1), one O(3), and one O(7) atom. In the second As site, As(2) is bonded in a 3-coordinate geometry to one O(1), one O(4), and one O(8) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a tetrahedral geometry to one O(3), one O(4), one O(5), and one O(6) atom. In the second S site, S(2) is bonded in a tetrahedral geometry to one O(10), one O(7), one O(8), and one O(9) atom. There are nine inequivalent O sites. In the first O site, O(9) is bonded in a single-bond geometry to one S(2) atom. In the second O site, O(10) is bonded in a single-bond geometry to one S(2) atom. In the third O site, O(1) is bonded in a bent 120 degrees geometry to one As(1) and one As(2) atom. In the fourth O site, O(3) is bonded in a distorted bent 120 degrees geometry to one As(1) and one S(1) atom. In the fifth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one As(2) and one S(1) atom. In the sixth O site, O(5) is bonded in a single-bond geometry to one S(1) atom. In the seventh O site, O(6) is bonded in a single-bond geometry to one S(1) atom. In the eighth O site, O(7) is bonded in a distorted bent 150 degrees geometry to one As(1) and one S(2) atom. In the ninth O site, O(8) is bonded in a distorted bent 150 degrees geometry to one As(2) and one S(2) atom. is represented by the CIF card [CIF]
