Materials Data on Sr2La2FeCu3O10 by Materials Project
Abstract
Sr2La2FeCu3O10 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to ten O2- atoms. There are a spread of Sr–O bond distances ranging from 2.59–3.06 Å. La3+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of La–O bond distances ranging from 2.52–2.85 Å. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with two equivalent FeO6 octahedra and corners with four equivalent CuO5 square pyramids. The corner-sharing octahedral tilt angles are 0°. There are a spread of Fe–O bond distances ranging from 1.99–2.01 Å. There are two inequivalent Cu+2.33+ sites. In the first Cu+2.33+ site, Cu+2.33+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.86 Å) and two longer (2.00 Å) Cu–O bond length. In the second Cu+2.33+ site, Cu+2.33+ is bonded to five O2- atoms to form CuO5 square pyramids that share corners with two equivalent FeO6 octahedra and corners with two equivalent CuO5 square pyramids. The corner-sharing octahedra tilt angles range from 14–25°. There are a spread of Cu–O bond distances ranging from 1.87–2.24 Å. There are six inequivalent O2- sites.more »
