K3Sb7(SO3)3 crystallizes in the hexagonal P6_3 space group. K(1) is bonded to one S(1), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing KSO6 hexagonal pyramids. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(3) atom. In the second Sb site, Sb(2) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(3) atom. In the third Sb site, Sb(3) is bonded in a trigonal non-coplanar geometry to three equivalent S(1) atoms. S(1) is bonded in a distorted bent 120 degrees geometry to one K(1) and one Sb(3) atom. There are three inequivalent O sites. In the first 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 second O site, O(2) is bonded to two equivalent K(1), one Sb(1), and one Sb(2) atom to form a mixture of distorted corner and edge-sharing OK2Sb2 tetrahedra. In the third O site, O(3) is bonded to two equivalent K(1), one Sb(1), and one Sb(2) atom to form a mixture of distorted corner and edge-sharing OK2Sb2 tetrahedra.
