Materials Data on Ba2Sm(CuO2)3 by Materials Project
Abstract
Ba2Sm(CuO2)3 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.82 Å) and four longer (2.94 Å) Ba–O bond lengths. Sm3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Sm–O bond lengths are 2.47 Å. There are two inequivalent Cu+1.67+ sites. In the first Cu+1.67+ site, Cu+1.67+ is bonded to five O2- atoms to form corner-sharing CuO5 square pyramids. There are four shorter (1.96 Å) and one longer (2.60 Å) Cu–O bond lengths. In the second Cu+1.67+ site, Cu+1.67+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.81 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Ba2+, two equivalent Sm3+, and two equivalent Cu+1.67+ atoms. In the second O2- site, O2- is bonded in a 6-coordinate geometry to four equivalent Ba2+ and two Cu+1.67+ atoms.
