Materials Data on BaSr(CuO2)2 by Materials Project
BaSr(CuO2)2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. All Ba–O bond lengths are 2.79 Å. Sr2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Sr–O bond lengths are 2.63 Å. Cu2+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.99 Å. O2- is bonded to two equivalent Ba2+, two equivalent Sr2+, and two equivalent Cu2+ atoms to form a mixture of distorted corner, edge, and face-sharing OBa2Sr2Cu2 octahedra. The corner-sharing octahedra tilt angles range from 0–65°.
