Materials Data on LuCd2 by Materials Project

Abstract

LuCd2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Lu is bonded to two equivalent Lu and six equivalent Cd atoms to form LuLu2Cd6 hexagonal bipyramids that share corners with two equivalent LuLu2Cd6 hexagonal bipyramids, corners with six equivalent CdLu3Cd5 hexagonal bipyramids, edges with six equivalent LuLu2Cd6 hexagonal bipyramids, and edges with eighteen equivalent CdLu3Cd5 hexagonal bipyramids. Both Lu–Lu bond lengths are 3.22 Å. All Lu–Cd bond lengths are 3.11 Å. Cd is bonded to three equivalent Lu and five equivalent Cd atoms to form distorted CdLu3Cd5 hexagonal bipyramids that share corners with three equivalent LuLu2Cd6 hexagonal bipyramids, corners with five equivalent CdLu3Cd5 hexagonal bipyramids, edges with nine equivalent LuLu2Cd6 hexagonal bipyramids, and edges with fifteen equivalent CdLu3Cd5 hexagonal bipyramids. There are three shorter (3.12 Å) and two longer (3.22 Å) Cd–Cd bond lengths.
