Materials Data on CeAsS by Materials Project

Abstract

CeAsS crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ce3+ is bonded in a 9-coordinate geometry to four equivalent As1- and five equivalent S2- atoms. There are a spread of Ce–As bond distances ranging from 3.15–3.21 Å. There are four shorter (2.87 Å) and one longer (2.90 Å) Ce–S bond lengths. As1- is bonded in a 8-coordinate geometry to four equivalent Ce3+ and four equivalent As1- atoms. There are a spread of As–As bond distances ranging from 2.63–2.97 Å. S2- is bonded to five equivalent Ce3+ atoms to form a mixture of distorted edge and corner-sharing SCe5 trigonal bipyramids.
