K2CoH4(SeO5)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.80–3.28 Å. Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with four equivalent SeO4 tetrahedra. There are a spread of Co–O bond distances ranging from 2.09–2.14 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 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. Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with two equivalent CoO6 octahedra. The corner-sharing octahedra tilt angles range from 48–52°. There are a spread of Se–O bond distances ranging from 1.66–1.70 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent K1+, one Co2+, and one Se6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one Co2+, and one Se6+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Se6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one Co2+, and two H1+ atoms.
