Abstract

H2V3O8 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent V+4.67+ sites. In the first V+4.67+ site, V+4.67+ is bonded in a 5-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.62–2.39 Å. In the second V+4.67+ site, V+4.67+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.73–2.25 Å. In the third V+4.67+ site, V+4.67+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of V–O bond distances ranging from 1.60–1.98 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.06 Å) and one longer (1.48 Å) H–O bond length. 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. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three V+4.67+ atoms. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one V+4.67+ and one H1+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one V+4.67+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted T-shaped geometry to three equivalent V+4.67+ atoms. In the fifth O2- site, O2- is bonded in a single-bond geometry to one V+4.67+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to four V+4.67+ atoms. In the seventh O2- site, O2- is bonded in a single-bond geometry to one V+4.67+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three V+4.67+ atoms.
