Materials Data on SrLaCoO4 by Materials Project
Abstract
LaSrCoO4 is (La,Ba)CuO4-derived structured and crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.46–2.75 Å. La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.36–2.74 Å. Co3+ is bonded to six O2- atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 6°. There are a spread of Co–O bond distances ranging from 1.93–2.13 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Sr2+, two equivalent La3+, and two equivalent Co3+ atoms to form distorted OSr2La2Co2 octahedra that share corners with fourteen OSrLa4Co octahedra, edges with two equivalent OSr2La2Co2 octahedra, and faces with eight OSrLa4Co octahedra. The corner-sharing octahedra tilt angles range from 6–53°. In the second O2- site, O2- is bonded to one Sr2+, four equivalent La3+, and one Co3+ atom to form distorted OSrLa4Co octahedra that share corners with seventeen OSrLa4Co octahedra, edges with eight OSrLa4Co octahedra, and faces with four equivalent OSr2La2Co2 octahedra. The corner-sharing octahedra tilt angles range frommore »
