The crystal structure described by Sb2S2O9 crystallizes in the tetragonal P4_12_12 space group. Sb(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form distorted SbO5 square pyramids that share  a cornercorner with one Sb(1)O5 square pyramid and corners with four equivalent S(1)O4 tetrahedra. S(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SO4 tetrahedra that share corners with four equivalent Sb(1)O5 square pyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Sb(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Sb(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to two equivalent Sb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
