Materials Data on SmCdCu by Materials Project

Abstract

SmCuCd crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Sm is bonded in a 11-coordinate geometry to five Cu and six equivalent Cd atoms. There are four shorter (3.04 Å) and one longer (3.16 Å) Sm–Cu bond lengths. There are two shorter (3.26 Å) and four longer (3.39 Å) Sm–Cd bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded in a 9-coordinate geometry to three equivalent Sm and six equivalent Cd atoms. All Cu–Cd bond lengths are 2.75 Å. In the second Cu site, Cu is bonded in a 9-coordinate geometry to six equivalent Sm and three equivalent Cd atoms. All Cu–Cd bond lengths are 2.93 Å. Cd is bonded in a 10-coordinate geometry to six equivalent Sm and four Cu atoms.
