Materials Data on Ba2Ca4TlCu5O13 by Materials Project
Abstract
Ba2Ca4Cu5TlO13 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.69–2.99 Å. There are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.47–2.54 Å. In the second Ca2+ site, Ca2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.38–2.62 Å. There are three inequivalent Cu+2.20+ sites. In the first Cu+2.20+ site, Cu+2.20+ is bonded to five O2- atoms to form distorted corner-sharing CuO5 square pyramids. There are a spread of Cu–O bond distances ranging from 1.93–2.61 Å. In the second Cu+2.20+ site, Cu+2.20+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There is two shorter (1.92 Å) and two longer (1.93 Å) Cu–O bond length. In the third Cu+2.20+ site, Cu+2.20+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.92 Å) and two longer (1.93 Å) Cu–O bond length. Tl3+ ismore »

In the first Cu+2.20+ site, Cu+2.20+ is bonded to five O2- atoms to form distorted corner-sharing CuO5 square pyramids. There are a spread of Cu–O bond distances ranging from 1.93–2.61 Å.

In the first O2- site, O2- is bonded to four Ca2+ and two equivalent Cu+2.20+ atoms to form a mixture of distorted corner, edge, and face-sharing OCa4Cu2 octahedra.

In the second O2- site, O2- is bonded to four Ca2+ and two equivalent Cu+2.20+ atoms to form a mixture of distorted corner, edge, and face-sharing OCa4Cu2 octahedra. The corner-sharing octahedra tilt angles range from 2–66°. In the third O2- site, O2- is bonded to four equivalent Ba2+, one Cu+2.20+, and one Tl3+ atom to form a mixture of distorted corner and edge-sharing OBa4TlCu octahedra. The corner-sharing octahedra tilt angles range from 17–23°. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, two equivalent Ca2+, and two equivalent Cu+2.20+ atoms. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, two equivalent Ca2+, and two equivalent Cu+2.20+ atoms. In the sixth O2- site, O2- is bonded in a see-saw-like geometry to two equivalent Ba2+ and two equivalent Tl3+ atoms. In the seventh O2- site, O2- is bonded to four equivalent Ca2+ and two equivalent Cu+2.20+ atoms to form a mixture of corner, edge, and face-sharing OCa4Cu2 octahedra.
