Materials Data on Sr3Nb2CoO9 by Materials Project
Abstract
Sr3Nb2CoO9 is Pb (Zr_0.50 Ti_0.48) O_3-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 6-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.52–3.11 Å. In the second Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.46–3.16 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 2.46–3.16 Å. There are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to four O2- atoms to form corner-sharing NbO4 tetrahedra. There are a spread of Nb–O bond distances ranging from 1.81–1.93 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with two equivalent NbO6 octahedra and corners with two equivalent CoO6 octahedra. The corner-sharing octahedra tilt angles range from 24–30°. There are a spread of Nb–O bond distances ranging from 1.96–2.09 Å. There are two inequivalent Co2+more »
