K3VMo3H4O15 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.67–3.01 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.89–3.17 Å. In the third K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.96–3.33 Å. V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.65–2.42 Å. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.74–2.50 Å. In the second Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.75–2.37 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 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom.

In the second O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one Mo6+ atom. In the third O2- site, O2- is bonded in a water-like geometry to two equivalent K1+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one V5+ and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one V5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one V5+, and two equivalent Mo6+ atoms. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to four K1+ and one Mo6+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+ and two Mo6+ atoms. In the tenth O2- site, O2- is bonded to two equivalent V5+ and three Mo6+ atoms to form distorted edge-sharing OV2Mo3 square pyramids.
