Title: Materials Data on Ba5Nb2O10 by Materials Project

Abstract

Ba5Nb2O10 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are five inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra and faces with six NbO6 octahedra. There are a spread of Ba–O bond distances ranging from 3.02–3.22 Å. In the second Ba2+ site, Ba2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.56–3.24 Å. In the third 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 2.57–3.24 Å. In the fourth 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 2.57–3.22 Å. In the fifth 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 2.50–3.24 Å. There are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form distorted NbO6 octahedra that share faces with threemore » equivalent BaO12 cuboctahedra and a faceface with one NbO6 octahedra. There are a spread of Nb–O bond distances ranging from 1.92–2.24 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share faces with three equivalent BaO12 cuboctahedra and a faceface with one NbO6 octahedra. There are a spread of Nb–O bond distances ranging from 1.93–2.19 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two Nb5+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to five Ba2+ and one Nb5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to five Ba2+ and one Nb5+ atom. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to five Ba2+ atoms. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to five Ba2+ and one Nb5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to five Ba2+ and one Nb5+ atom. In the seventh O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two Nb5+ atoms.« less
