Materials Data on VPH5O7 by Materials Project

VP(HO2)3H2O crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four water molecules and one VP(HO2)3 sheet oriented in the (1, 0, 0) direction. In the VP(HO2)3 sheet, V4+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with two equivalent VO6 octahedra and corners with three equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 33°. There are a spread of V–O bond distances ranging from 1.69–2.13 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent VO6 octahedra. The corner-sharing octahedra tilt angles range from 34–51°. There are a spread of P–O bond distances ranging from 1.53–1.59 Å. There are three 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 1.00 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one V4+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one V4+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one V4+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent V4+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one V4+ and one P5+ atom.
