Abstract

H2V3O8(H2O)2 crystallizes in the monoclinic Pc space group. The structure is two-dimensional and consists of four water molecules and one H2V3O8 sheet oriented in the (1, 0, 0) direction. In the H2V3O8 sheet, there are three inequivalent V+4.67+ sites. In the first V+4.67+ site, V+4.67+ is bonded to five O2- atoms to form distorted corner-sharing VO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 1.62–2.01 Å. In the second V+4.67+ site, V+4.67+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one VO4 tetrahedra and corners with two equivalent VO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 1.70–1.82 Å. In the third V+4.67+ site, V+4.67+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one VO4 tetrahedra and corners with two equivalent VO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 1.71–1.79 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 1.01 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. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two V+4.67+ atoms. In the second O2- site, O2- is bonded in a single-bond geometry to one V+4.67+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two V+4.67+ atoms. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two V+4.67+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two V+4.67+ atoms. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two V+4.67+ atoms. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one V+4.67+ and one H1+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one V+4.67+ and one H1+ atom.
