Materials Data on Ce2Si2NiPt by Materials Project

Abstract

Ce2PtNiSi2 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are two inequivalent Ce4+ sites. In the first Ce4+ site, Ce4+ is bonded in a 8-coordinate geometry to two equivalent Pt2- and six Si4- atoms. Both Ce–Pt bond lengths are 3.13 Å. There are four shorter (3.09 Å) and two longer (3.11 Å) Ce–Si bond lengths. In the second Ce4+ site, Ce4+ is bonded in a 10-coordinate geometry to four equivalent Pt2- and six Si4- atoms. All Ce–Pt bond lengths are 3.14 Å. There are four shorter (3.12 Å) and two longer (3.23 Å) Ce–Si bond lengths. Pt2- is bonded in a 3-coordinate geometry to six Ce4+ and three Si4- atoms. There are two shorter (2.45 Å) and one longer (2.47 Å) Pt–Si bond lengths. Ni2+ is bonded in a trigonal planar geometry to three Si4- atoms. There are two shorter (2.29 Å) and one longer (2.31 Å) Ni–Si bond lengths. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 2-coordinate geometry to six Ce4+, two equivalent Pt2-, and one Ni2+ atom. In the second Si4- site, Si4- is bonded in a 1-coordinate geometry to six Ce4+, one Pt2-, and two equivalent Ni2+ atoms.
