(K(H2O)3)2(H2O)2H2O2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four water molecules; four water molecules; and one K(H2O)3 sheet oriented in the (1, 0, 0) direction. In the K(H2O)3 sheet, K1+ is bonded in a 3-coordinate geometry to two H1+ and six O2- atoms. There are one shorter (2.79 Å) and one longer (2.81 Å) K–H bond lengths. There are a spread of K–O bond distances ranging from 2.73–3.03 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one O2- atom. The H–O bond length is 1.00 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one O2- atom. The H–O bond length is 1.00 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to two equivalent K1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent K1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a water-like geometry to two equivalent K1+ and two H1+ atoms.
