Materials Data on LuInCu2 by Materials Project

LuInCu2 is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Lu is bonded in a body-centered cubic geometry to eight equivalent Cu and six equivalent In atoms. All Lu–Cu bond lengths are 2.84 Å. All Lu–In bond lengths are 3.28 Å. Cu is bonded in a body-centered cubic geometry to four equivalent Lu and four equivalent In atoms. All Cu–In bond lengths are 2.84 Å. In is bonded in a distorted body-centered cubic geometry to six equivalent Lu and eight equivalent Cu atoms.

Materials Data on Lu2InCu2 by Materials Project

Lu2Cu2In crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Lu is bonded in a 6-coordinate geometry to six equivalent Cu and four equivalent In atoms. There are two shorter (2.83 Å) and four longer (2.84 Å) Lu–Cu bond lengths. All Lu–In bond lengths are 3.29 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Lu, one Cu, and two equivalent In atoms. The Cu–Cu bond length is 2.54 Å. Both Cu–In bond lengths are 3.00 Å. In is bonded to eight equivalent Lu and four equivalent Cu atoms to form a mixture of corner and face-sharing InLu8Cu4 cuboctahedra.
