Materials Data on CeNiSn2 by Materials Project
CeNiSn2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce is bonded in a 6-coordinate geometry to four equivalent Ni and ten Sn atoms. All Ce–Ni bond lengths are 3.43 Å. There are a spread of Ce–Sn bond distances ranging from 3.36–3.59 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Ce and five Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.45–2.58 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 1-coordinate geometry to six equivalent Ce, one Ni, and two equivalent Sn atoms. Both Sn–Sn bond lengths are 2.82 Å. In the second Sn site, Sn is bonded in a 12-coordinate geometry to four equivalent Ce and four equivalent Ni atoms.
