The structure described by SbO2 crystallizes in the triclinic P-1 space group. There are four inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one O(1), one O(6), one O(7), and two equivalent O(3) atoms to form edge-sharing SbO5 trigonal bipyramids. In the second Sb site, Sb(2) is bonded in a tetrahedral geometry to one O(2), one O(4), one O(5), and one O(8) atom. In the third Sb site, Sb(3) is bonded in a distorted T-shaped geometry to one O(1), one O(5), and one O(8) atom. In the fourth Sb site, Sb(4) is bonded in a rectangular see-saw-like geometry to one O(2), one O(4), one O(6), and one O(7) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Sb(1) and one Sb(3) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sb(2) and one Sb(4) atom. In the third O site, O(3) is bonded in a water-like geometry to two equivalent Sb(1) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Sb(2) and one Sb(4) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Sb(2) and one Sb(3) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Sb(1) and one Sb(4) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one Sb(1) and one Sb(4) atom. In the eighth O site, O(8) is bonded in a bent 120 degrees geometry to one Sb(2) and one Sb(3) atom. is represented by the CIF card [CIF]
