Materials Data on Tb6RhBr10 by Materials Project

Abstract

Tb6RhBr10 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Tb sites. In the first Tb site, Tb is bonded to one Rh and five Br atoms to form a mixture of edge and corner-sharing TbRhBr5 octahedra. The corner-sharing octahedra tilt angles range from 0–4°. The Tb–Rh bond length is 2.74 Å. There are a spread of Tb–Br bond distances ranging from 2.82–3.08 Å. In the second Tb site, Tb is bonded to one Rh and five Br atoms to form a mixture of edge and corner-sharing TbRhBr5 octahedra. The corner-sharing octahedra tilt angles range from 0–3°. The Tb–Rh bond length is 2.71 Å. There are a spread of Tb–Br bond distances ranging from 2.85–3.10 Å. In the third Tb site, Tb is bonded to one Rh and five Br atoms to form a mixture of edge and corner-sharing TbRhBr5 octahedra. The corner-sharing octahedra tilt angles range from 0–4°. The Tb–Rh bond length is 2.68 Å. There are a spread of Tb–Br bond distances ranging from 2.91–3.11 Å. Rh is bonded in an octahedral geometry to six Tb atoms. There are five inequivalent Br sites. In the first Br site, Br is bonded in an L-shaped geometry to two Tb atoms. In the second Br site, Br is bonded in a see-saw-like geometry to four Tb atoms. In the third Br site, Br is bonded in a 3-coordinate geometry to three Tb atoms. In the fourth Br site, Br is bonded in a T-shaped geometry to three Tb atoms. In the fifth Br site, Br is bonded in a T-shaped geometry to three Tb atoms.
