Abstract

(VPH4O7)2(H2)5(H2O2)2 crystallizes in the tetragonal P4_1 space group. The structure is one-dimensional and consists of twelve dihydrogen molecules; four water water molecules; and two VPH4O7 ribbons oriented in the (0, 0, 1) direction. In each VPH4O7 ribbon, V2+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with three equivalent PO4 tetrahedra. There are a spread of V–O bond distances ranging from 1.64–2.24 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 5–31°. There are a spread of P–O bond distances ranging from 1.52–1.64 Å. There are four 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 0.99 Å. In the third 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 fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one V2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one V2+ and one H1+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one V2+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to one V2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a water-like geometry to one P5+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one V2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one V2+ and one P5+ atom.
