CsVSeO5 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Cs–O bond distances ranging from 3.06–3.60 Å. In the second Cs1+ site, Cs1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Cs–O bond distances ranging from 3.13–3.52 Å. There are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded in a distorted trigonal bipyramidal geometry to five O2- atoms. There are a spread of V–O bond distances ranging from 1.65–2.01 Å. In the second V5+ site, V5+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of V–O bond distances ranging from 1.65–2.08 Å. There are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.73–1.75 Å. In the second Se4+ site, Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.71–1.76 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to three Cs1+ and one V5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Cs1+, one V5+, and one Se4+ atom.
