Title: Materials Data on TaAsO4 by Materials Project

Abstract

TaAsO4 crystallizes in the orthorhombic Pnna space group. The structure is three-dimensional. Ta5+ is bonded to six O2- atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedral tilt angles are 35°. There are a spread of Ta–O bond distances ranging from 1.92–2.08 Å. As3+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent O2- atoms. There are two shorter (1.85 Å) and two longer (2.16 Å) As–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ta5+ and two equivalent As3+ atoms. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Ta5+ atoms.
