Abstract

SnTa2O6 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Ta5+ sites. In the first Ta5+ site, 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 30–56°. There are a spread of Ta–O bond distances ranging from 1.89–2.17 Å. In the second Ta5+ site, 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 30–55°. There are a spread of Ta–O bond distances ranging from 1.89–2.16 Å. Sn2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Sn–O bond distances ranging from 2.18–2.47 Å. There are six 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 trigonal planar geometry to three Ta5+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinatemore »« less
