Title: Materials Data on Ta2H4O7 by Materials Project

Abstract

H4OTa2O6 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional and consists of eight water molecules and one HTaO3 framework. In the HTaO3 framework, Ta5+ is bonded to six O2- atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedra tilt angles range from 32–47°. There are a spread of Ta–O bond distances ranging from 1.94–2.10 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Ta5+ atoms. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Ta5+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ta5+ and one H1+ atom.
