Materials Data on CeAgAs2 by Materials Project

Abstract

CeAgAs2 crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. Ce3+ is bonded in a 8-coordinate geometry to eight As2- atoms. There are three shorter (3.04 Å) and five longer (3.05 Å) Ce–As bond lengths. Ag1+ is bonded in a 8-coordinate geometry to four equivalent Ag1+ and four equivalent As2- atoms. All Ag–Ag bond lengths are 2.90 Å. There are a spread of Ag–As bond distances ranging from 2.79–2.84 Å. There are two inequivalent As2- sites. In the first As2- site, As2- is bonded in a 8-coordinate geometry to four equivalent Ce3+ and four equivalent Ag1+ atoms. In the second As2- site, As2- is bonded in a 8-coordinate geometry to four equivalent Ce3+ and four equivalent As2- atoms. All As–As bond lengths are 2.90 Å.
