Abstract

Ba8Bi4O17 is Pb(Zr_(1-x)Ti_x)O3-like structured and crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. there are five inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–3.37 Å. In the second Ba2+ site, Ba2+ is bonded to six O2- atoms to form distorted BaO6 pentagonal pyramids that share corners with two BiO6 octahedra and corners with four equivalent BiO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 0°. There are a spread of Ba–O bond distances ranging from 2.51–2.65 Å. In the third Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.80–3.33 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.88–3.24 Å. In the fifth Ba2+ site, Ba2+ is bonded to five O2- atoms to form distorted BaO5 square pyramids that share corners with five BiO6 octahedra. The corner-sharing octahedra tilt angles range from 0–16°.
