Materials Data on Bi2Rh3S2 by Materials Project

Abstract

Rh3Bi2S2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Rh sites. In the first Rh site, Rh is bonded in a 2-coordinate geometry to four Bi and two equivalent S atoms. There are two shorter (2.92 Å) and two longer (2.96 Å) Rh–Bi bond lengths. Both Rh–S bond lengths are 2.32 Å. In the second Rh site, Rh is bonded in a 2-coordinate geometry to four Bi and two equivalent S atoms. There are two shorter (2.92 Å) and two longer (2.93 Å) Rh–Bi bond lengths. Both Rh–S bond lengths are 2.32 Å. In the third Rh site, Rh is bonded in a 6-coordinate geometry to four Bi and two equivalent S atoms. There are a spread of Rh–Bi bond distances ranging from 2.86–3.02 Å. Both Rh–S bond lengths are 2.31 Å. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 8-coordinate geometry to six Rh and two equivalent S atoms. Both Bi–S bond lengths are 3.28 Å. In the second Bi site, Bi is bonded in a distorted hexagonal planar geometry to six Rh atoms. S is bonded in a 3-coordinate geometry to three Rh and one Bi atom.
