Materials Data on Ce2NiPt by Materials Project

Abstract

Ce2PtNi crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 7-coordinate geometry to four equivalent Pt and three equivalent Ni atoms. All Ce–Pt bond lengths are 2.91 Å. There are one shorter (2.98 Å) and two longer (3.10 Å) Ce–Ni bond lengths. In the second Ce site, Ce is bonded in a 7-coordinate geometry to three equivalent Pt and four equivalent Ni atoms. There are two shorter (3.04 Å) and one longer (3.05 Å) Ce–Pt bond lengths. All Ce–Ni bond lengths are 2.90 Å. Pt is bonded in a 9-coordinate geometry to seven Ce and two equivalent Ni atoms. Both Pt–Ni bond lengths are 2.88 Å. Ni is bonded in a 9-coordinate geometry to seven Ce and two equivalent Pt atoms.
