Materials Data on CeSbSe by Materials Project
CeSbSe is Matlockite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ce3+ is bonded in a 5-coordinate geometry to four equivalent Sb1- and five equivalent Se2- atoms. There are a spread of Ce–Sb bond distances ranging from 3.35–3.40 Å. There are a spread of Ce–Se bond distances ranging from 3.02–3.08 Å. Sb1- is bonded in a 8-coordinate geometry to four equivalent Ce3+ and four equivalent Sb1- atoms. There are a spread of Sb–Sb bond distances ranging from 2.99–3.02 Å. Se2- is bonded to five equivalent Ce3+ atoms to form a mixture of distorted edge and corner-sharing SeCe5 square pyramids.
