Materials Data on Sr2HoCu2RuO8 by Materials Project
Abstract
RuSr2HoCu2O8 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with eight equivalent SrO12 cuboctahedra, faces with five equivalent SrO12 cuboctahedra, faces with four equivalent RuO6 octahedra, and faces with four equivalent CuO5 square pyramids. There are a spread of Sr–O bond distances ranging from 2.67–3.03 Å. Ho3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are two shorter (2.39 Å) and six longer (2.40 Å) Ho–O bond lengths. Ru5+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with four equivalent RuO6 octahedra, corners with two equivalent CuO5 square pyramids, and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is four shorter (1.92 Å) and two longer (2.05 Å) Ru–O bond length. Cu2+ is bonded to five O2- atoms to form CuO5 square pyramids that share a cornercorner with one RuO6 octahedra, corners with four equivalent CuO5 square pyramids, and faces with four equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 2°. There are a spread of Cu–O bond distances ranging from 1.93–2.21 Å. There are four inequivalentmore »

In the first O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Sr2+, two equivalent Ho3+, and two equivalent Cu2+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+, two equivalent Ho3+, and two equivalent Cu2+ atoms. In the third O2- site, O2- is bonded to four equivalent Sr2+, one Ru5+, and one Cu2+ atom to form a mixture of distorted edge and corner-sharing OSr4CuRu octahedra. The corner-sharing octahedra tilt angles range from 0–11°. In the fourth O2- site, O2- is bonded in a linear geometry to four equivalent Sr2+ and two equivalent Ru5+ atoms.},
