Materials Data on Sr3TbRhO6 by Materials Project
Sr3TbRhO6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are a spread of Sr–O bond distances ranging from 2.54–2.77 Å. Tb3+ is bonded to six equivalent O2- atoms to form distorted TbO6 pentagonal pyramids that share faces with two equivalent RhO6 octahedra. All Tb–O bond lengths are 2.30 Å. Rh3+ is bonded to six equivalent O2- atoms to form RhO6 octahedra that share faces with two equivalent TbO6 pentagonal pyramids. All Rh–O bond lengths are 2.11 Å. O2- is bonded to four equivalent Sr2+, one Tb3+, and one Rh3+ atom to form a mixture of distorted edge, face, and corner-sharing OSr4TbRh octahedra. The corner-sharing octahedra tilt angles range from 0–66°.
