The material structure described by K2(SO2)3 crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 9-coordinate geometry to one O(3), two equivalent O(1), two equivalent O(4), and four equivalent O(2) atoms. In the second K site, K(2) is bonded in a 9-coordinate geometry to one O(4), two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a trigonal non-coplanar geometry to one S(2), one O(3), and two equivalent O(1) atoms. In the second S site, S(2) is bonded in a water-like geometry to one S(1) and one S(3) atom. In the third S site, S(3) is bonded in a trigonal non-coplanar geometry to one S(2), one O(4), and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(3) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one S(1) atom. In the second O site, O(4) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one S(3) atom. In the third O site, O(1) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one S(1) atom. In the fourth O site, O(2) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one S(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
