The material described by KSb(SO4)2 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 10-coordinate geometry to one O(4), one O(7), one O(8), two equivalent O(1), two equivalent O(5), and three equivalent O(6) atoms. Sb(1) is bonded in a distorted rectangular see-saw-like geometry to one O(3), one O(4), one O(7), 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(1), one O(2), one O(3), and one O(4) atom. In the second S site, S(2) is bonded in a tetrahedral geometry to one O(5), one O(6), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(5) is bonded in a distorted single-bond geometry to two equivalent K(1) and one S(2) atom. In the second O site, O(6) is bonded in a distorted single-bond geometry to three equivalent K(1) and one S(2) atom. In the third O site, O(7) is bonded in a 1-coordinate geometry to one K(1), one Sb(1), and one S(2) atom. In the fourth O site, O(8) is bonded in a distorted bent 120 degrees geometry to one K(1), one Sb(1), and one S(2) atom. In the fifth O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one S(1) atom. In the sixth O site, O(2) is bonded in a single-bond geometry to one S(1) atom. In the seventh O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Sb(1) and one S(1) atom.
