Materials Data on Ba2Y(CuO2)3 by Materials Project
Abstract
YBa2Cu3O6 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 (2.84 Å) and four longer (2.91 Å) Ba–O bond lengths. Y3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Y–O bond lengths are 2.43 Å. There are two inequivalent Cu+1.67+ sites. In the first Cu+1.67+ site, Cu+1.67+ is bonded in a distorted rectangular see-saw-like geometry to five O2- atoms. There are four shorter (1.95 Å) and one longer (2.79 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 1.80 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 Y3+, and two equivalent Cu+1.67+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to four equivalent Ba2+ and two Cu+1.67+ atoms.
