Abstract

Ta2O5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ta5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing TaO6 octahedra. The corner-sharing octahedra tilt angles range from 27–55°. There are a spread of Ta–O bond distances ranging from 1.85–2.17 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three 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 bent 150 degrees geometry to two equivalent Ta5+ atoms.
