Materials Data on Ba2Ho2CuPtO8 by Materials Project
Abstract
Ba2Ho2PtCuO8 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Ba–O bond distances ranging from 2.87–3.39 Å. In the second Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.66–3.25 Å. There are two inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to seven O2- atoms to form distorted HoO7 pentagonal bipyramids that share a cornercorner with one HoO7 pentagonal bipyramid, corners with two equivalent CuO5 square pyramids, edges with five HoO7 pentagonal bipyramids, an edgeedge with one CuO5 square pyramid, and a faceface with one PtO6 octahedra. There are a spread of Ho–O bond distances ranging from 2.29–2.42 Å. In the second Ho3+ site, Ho3+ is bonded to seven O2- atoms to form distorted HoO7 pentagonal bipyramids that share corners with two equivalent PtO6 octahedra, a cornercorner with one HoO7 pentagonal bipyramid, edges with three equivalent HoO7 pentagonal bipyramids, edges with two equivalent CuO5 square pyramids, and a faceface with one PtO6 octahedra.more »

The corner-sharing octahedral tilt angles are 12°. There are a spread of Ho–O bond distances ranging from 2.25–2.45 Å. Pt5+ is bonded to six O2- atoms to form PtO6 octahedra that share corners with two equivalent HoO7 pentagonal bipyramids, corners with three equivalent CuO5 square pyramids, and faces with two HoO7 pentagonal bipyramids.

In the first O2- site, O2- is bonded to three Ba2+, one Ho3+, one Pt5+, and one Cu1+ atom to form a mixture of distorted edge, corner, and face-sharing OBa3HoCuPt octahedra. The corner-sharing octahedra tilt angles range from 55–68°. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two Ba2+, three Ho3+, and one Cu1+ atom. In the third O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+, one Pt5+, and one Cu1+ atom. In the fourth O2- site, O2- is bonded to three Ba2+, two Ho3+, and one Pt5+ atom to form a mixture of distorted corner and face-sharing OBa3Ho2Pt octahedra. The corner-sharing octahedra tilt angles range from 2–68°. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to three Ba2+, two Ho3+, and one Pt5+ atom.},
