KVH6SeO9 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. K1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.83–3.21 Å. V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.65–2.27 Å. There are six 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 0.98 Å. In the third 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 fourth 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 fifth 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 sixth 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 in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.65–1.70 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one Se6+ atom. In the second O2- site, O2- is bonded in a water-like geometry to one K1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to two equivalent K1+ and one V5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one V5+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one V5+, and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one V5+, and two H1+ atoms. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one K1+, one V5+, and one Se6+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one V5+, and one Se6+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one Se6+ atom.
