Materials Data on Bi2S3 by Materials Project

Bi2S3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Bi–S bond distances ranging from 2.70–3.08 Å. In the second Bi3+ site, Bi3+ is bonded in a 5-coordinate geometry to seven S2- atoms. There are a spread of Bi–S bond distances ranging from 2.63–3.43 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded to five Bi3+ atoms to form distorted edge-sharing SBi5 square pyramids. In the second S2- site, S2- is bonded in a 5-coordinate geometry to five Bi3+ atoms. In the third S2- site, S2- is bonded in a 3-coordinate geometry to three Bi3+ atoms.
