K2SeS2O6 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two hydrogen sulfide atoms, two sulfur monoxide molecules, two K2SeO3 clusters, two KO3 clusters, one KS2O3 cluster, and one SeO2 cluster. In each K2SeO3 cluster, there are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one O(2) and one O(7) atom. The K(1)-O(2) bond length is 0.79 Å. The K(1)-O(7) bond length is 2.08 Å. In the second K site, K(3) is bonded in a single-bond geometry to one O(1) and one O(7) atom. The K(3)-O(1) bond length is 0.69 Å. The K(3)-O(7) bond length is 3.19 Å. Se(2) is bonded in a distorted single-bond geometry to one O(2) atom. The Se(2)-O(2) bond length is 2.44 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one K(3) atom. In the second O site, O(2) is bonded in a single-bond geometry to one K(1) and one Se(2) atom. In the third O site, O(7) is bonded in a distorted single-bond geometry to one K(1) and one K(3) atom. In each KO3 cluster, K(2) is bonded in a single-bond geometry to one O(4) and one O(6) atom. The K(2)-O(4) bond length is 2.08 Å. The K(2)-O(6) bond length is 0.60 Å. There are three inequivalent O sites. In the first O site, O(12) is bonded in a single-bond geometry to one O(6) atom. The O(12)-O(6) bond length is 1.19 Å. In the second O site, O(6) is bonded in a single-bond geometry to one K(2) and one O(12) atom. In the third O site, O(4) is bonded in a distorted single-bond geometry to one K(2) atom. In the KS2O3 cluster, K(4) is bonded in a single-bond geometry to one S(1), one O(3), one O(8), and one O(9) atom. The K(4)-S(1) bond length is 2.59 Å. The K(4)-O(3) bond length is 1.49 Å. The K(4)-O(8) bond length is 0.68 Å. The K(4)-O(9) bond length is 2.63 Å. There are two inequivalent S sites. In the first S site, S(1) is bonded in a water-like geometry to one K(4) and one O(8) atom. The S(1)-O(8) bond length is 2.41 Å. In the second S site, S(2) is bonded in a single-bond geometry to one O(3) atom. The S(2)-O(3) bond length is 0.85 Å. There are three inequivalent O sites. In the first O site, O(3) is bonded in a distorted L-shaped geometry to one K(4) and one S(2) atom. In the second O site, O(8) is bonded in a single-bond geometry to one K(4) and one S(1) atom. In the third O site, O(9) is bonded in a distorted single-bond geometry to one K(4) atom. In the SeO2 cluster, Se(1) is bonded in a 3-coordinate geometry to one Se(1), one O(11), and one O(5) atom. The Se(1)-Se(1) bond length is 0.53 Å. The Se(1)-O(11) bond length is 2.47 Å. The Se(1)-O(5) bond length is 2.34 Å. There are two inequivalent O sites. In the first O site, O(11) is bonded in a distorted single-bond geometry to one Se(1) and one O(5) atom. The O(11)-O(5) bond length is 0.65 Å. In the second O site, O(5) is bonded in an L-shaped geometry to one Se(1) and one O(11) atom.
