Abstract

SrSb2O6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Sr2+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are a spread of Sr–O bond distances ranging from 2.55–2.85 Å. There are four inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 47–51°. There are a spread of Sb–O bond distances ranging from 1.98–2.02 Å. In the second Sb5+ site, Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 45–51°. There are four shorter (2.00 Å) and two longer (2.03 Å) Sb–O bond lengths. In the third Sb5+ site, Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 45–49°. There are a spread of Sb–O bond distances ranging from 1.98–2.02 Å. In the fourth Sb5+ site, Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 45–51°. There are a spread of Sb–O bond distances ranging from 1.99–2.02 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Sr2+ and two Sb5+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+ and two Sb5+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two Sb5+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+ and two Sb5+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+ and two Sb5+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Sb5+ atoms.
