Materials Data on CeSn2Rh by Materials Project

Abstract

CeRhSn2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 8-coordinate geometry to six equivalent Rh and nine Sn atoms. There are four shorter (3.44 Å) and two longer (3.57 Å) Ce–Rh bond lengths. There are a spread of Ce–Sn bond distances ranging from 3.22–3.54 Å. In the second Ce site, Ce is bonded in a 4-coordinate geometry to four equivalent Rh and ten Sn atoms. All Ce–Rh bond lengths are 3.42 Å. There are a spread of Ce–Sn bond distances ranging from 3.53–3.68 Å. Rh is bonded in a 10-coordinate geometry to five Ce and five Sn atoms. There are a spread of Rh–Sn bond distances ranging from 2.64–2.79 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 3-coordinate geometry to four Ce and three equivalent Rh atoms. In the second Sn site, Sn is bonded in a 2-coordinate geometry to five Ce, two equivalent Rh, and one Sn atom. The Sn–Sn bond length is 2.83 Å. In the third Sn site, Sn is bonded in a 9-coordinate geometry to six Ce, two equivalent Rh, and one Sn atom.
