Materials Data on Ce(GePt)2 by Materials Project

Ce(PtGe)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce is bonded in a 12-coordinate geometry to eight Pt and eight Ge atoms. There are four shorter (3.34 Å) and four longer (3.35 Å) Ce–Pt bond lengths. There are four shorter (3.30 Å) and four longer (3.35 Å) Ce–Ge bond lengths. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a 4-coordinate geometry to four equivalent Ce and four equivalent Ge atoms. All Pt–Ge bond lengths are 2.55 Å. In the second Pt site, Pt is bonded in a 5-coordinate geometry to four equivalent Ce and five Ge atoms. There are one shorter (2.46 Å) and four longer (2.52 Å) Pt–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Ce and four equivalent Pt atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Ce and five Pt atoms.
