(Sb3O13)2O2 crystallizes in the monoclinic P2_1/m space group. The structure consists of two water atoms inside a Sb3O13 framework. In the Sb3O13 framework, there are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to two equivalent O(3), two equivalent O(6), and two equivalent O(7) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 39-60°. In the second Sb site, Sb(2) is bonded to one O(3), one O(4), one O(5), one O(8), and two equivalent O(6) atoms to form a mixture of corner and edge-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 39-60°. There are seven inequivalent O sites. In the first O site, O(2) is bonded in a water-like geometry to two equivalent O(5) atoms. In the second O site, O(3) is bonded in a bent 150 degrees geometry to one Sb(1) and one Sb(2) atom. In the third O site, O(4) is bonded in a single-bond geometry to one Sb(2) atom. In the fourth O site, O(5) is bonded in a water-like geometry to one Sb(2) and one O(2) atom. In the fifth O site, O(6) is bonded in a trigonal planar geometry to one Sb(1) and two equivalent Sb(2) atoms. In the sixth O site, O(7) is bonded in a single-bond geometry to one Sb(1) atom. In the seventh O site, O(8) is bonded in a single-bond geometry to one Sb(2) atom.
