Abstract

Sr6Nb2O11 is Pb (Zr_0.50 Ti_0.48) O_3-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are twelve inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 2-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.34–3.26 Å. In the second Sr2+ site, Sr2+ is bonded to five O2- atoms to form distorted SrO5 square pyramids that share corners with three equivalent NbO6 octahedra and corners with two equivalent NbO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 10–45°. There are a spread of Sr–O bond distances ranging from 2.14–2.73 Å. In the third Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.63–2.89 Å.
