The structure described by KSb3O5 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(4), two equivalent O(1), and two equivalent O(5) atoms. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), one O(4), and one O(5) atom. In the second Sb site, Sb(2) is bonded in a rectangular see-saw-like geometry to one O(1), one O(3), and two equivalent O(4) atoms. In the third Sb site, Sb(3) is bonded in a 3-coordinate geometry to one O(2), one O(3), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(5) is bonded to two equivalent K(1), one Sb(1), and one Sb(3) atom to form distorted corner-sharing OK2Sb2 trigonal pyramids. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent K(1), one Sb(1), and one Sb(2) atom. In the third O site, O(2) is bonded in a trigonal planar geometry to one K(1), one Sb(1), and one Sb(3) atom. In the fourth O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one K(1), one Sb(2), and one Sb(3) atom. In the fifth O site, O(4) is bonded in a 4-coordinate geometry to one K(1), one Sb(1), and two equivalent Sb(2) atoms. is represented by the CIF card [CIF]
