Materials Data on CeIr3 by Materials Project
Abstract
CeIr3 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a distorted hexagonal planar geometry to eighteen Ir atoms. There are six shorter (3.08 Å) and twelve longer (3.45 Å) Ce–Ir bond lengths. In the second Ce site, Ce is bonded in a 12-coordinate geometry to twelve Ir atoms. There are a spread of Ce–Ir bond distances ranging from 3.06–3.35 Å. There are three inequivalent Ir sites. In the first Ir site, Ir is bonded to six equivalent Ce and six equivalent Ir atoms to form IrCe6Ir6 cuboctahedra that share corners with twelve equivalent IrCe5Ir7 cuboctahedra, edges with six equivalent IrCe6Ir6 cuboctahedra, and faces with eighteen equivalent IrCe5Ir7 cuboctahedra. All Ir–Ir bond lengths are 2.72 Å. In the second Ir site, Ir is bonded in a 12-coordinate geometry to three equivalent Ce and nine Ir atoms. There are a spread of Ir–Ir bond distances ranging from 2.67–3.08 Å. In the third Ir site, Ir is bonded to five Ce and seven Ir atoms to form distorted IrCe5Ir7 cuboctahedra that share corners with seventeen IrCe6Ir6 cuboctahedra, edges with eight equivalent IrCe5Ir7 cuboctahedra, and facesmore »
