Materials Data on Ce2NiSn2Pt by Materials Project

Abstract

Ce2PtNiSn2 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 1-coordinate geometry to two equivalent Pt, four equivalent Ni, and six Sn atoms. There are one shorter (3.00 Å) and one longer (3.56 Å) Ce–Pt bond lengths. There are two shorter (3.18 Å) and two longer (3.34 Å) Ce–Ni bond lengths. There are a spread of Ce–Sn bond distances ranging from 3.15–3.33 Å. In the second Ce site, Ce is bonded in a 12-coordinate geometry to four equivalent Pt, two equivalent Ni, and six Sn atoms. There are two shorter (3.23 Å) and two longer (3.27 Å) Ce–Pt bond lengths. There are one shorter (3.05 Å) and one longer (3.50 Å) Ce–Ni bond lengths. There are a spread of Ce–Sn bond distances ranging from 3.26–3.39 Å. Pt is bonded in a 9-coordinate geometry to six Ce and four Sn atoms. There are a spread of Pt–Sn bond distances ranging from 2.74–2.96 Å. Ni is bonded in a 10-coordinate geometry to six Ce and four Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.63–2.82 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 10-coordinate geometry to six Ce, two equivalent Pt, and two equivalent Ni atoms. In the second Sn site, Sn is bonded in a 10-coordinate geometry to six Ce, two equivalent Pt, and two equivalent Ni atoms.
