Materials Data on Ba2Ca2Tl2Cu3O10 by Materials Project
Tl2Ba2Ca2Cu3O10 crystallizes in the orthorhombic Imm2 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 2.78–3.09 Å. Ca2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.49 Å) and four longer (2.54 Å) Ca–O bond lengths. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.94 Å) and two longer (1.95 Å) Cu–O bond length. In the second Cu2+ site, Cu2+ is bonded in a rectangular see-saw-like geometry to five O2- atoms. There are a spread of Cu–O bond distances ranging from 1.94–2.80 Å. Tl3+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Tl–O bond distances ranging from 2.06–2.46 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to four equivalent Ba2+, one Cu2+, and one Tl3+ atom. In the second O2- site, O2- is bonded to two equivalent Ba2+, two equivalent Ca2+, and two equivalent Cu2+ atoms to form distorted OBa2Ca2Cu2 octahedra that share corners with eight OBa2Ca2Cu2 octahedra, edges with three OCa4Cu2 octahedra, and faces with four equivalent OBa2Ca2Cu2 octahedra. The corner-sharing octahedra tilt angles range from 1–66°. In the third O2- site, O2- is bonded to two equivalent Ba2+, two equivalent Ca2+, and two equivalent Cu2+ atoms to form distorted OBa2Ca2Cu2 octahedra that share corners with eight OBa2Ca2Cu2 octahedra, edges with three OCa4Cu2 octahedra, and faces with four equivalent OBa2Ca2Cu2 octahedra. The corner-sharing octahedra tilt angles range from 1–66°. In the fourth O2- site, O2- is bonded to four equivalent Ca2+ and two equivalent Cu2+ atoms to form a mixture of edge, corner, and face-sharing OCa4Cu2 octahedra. The corner-sharing octahedra tilt angles range from 0–66°. In the fifth O2- site, O2- is bonded to four equivalent Ca2+ and two equivalent Cu2+ atoms to form a mixture of edge, corner, and face-sharing OCa4Cu2 octahedra. The corner-sharing octahedra tilt angles range from 0–66°. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to one Ba2+ and three equivalent Tl3+ atoms.
