Materials Data on PrInCu2 by Materials Project

PrInCu2 is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pr is bonded in a distorted body-centered cubic geometry to eight equivalent Cu and six equivalent In atoms. All Pr–Cu bond lengths are 2.95 Å. All Pr–In bond lengths are 3.41 Å. Cu is bonded in a body-centered cubic geometry to four equivalent Pr and four equivalent In atoms. All Cu–In bond lengths are 2.95 Å. In is bonded in a 8-coordinate geometry to six equivalent Pr and eight equivalent Cu atoms.

Materials Data on Pr2InCu2 by Materials Project

Pr2Cu2In crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Pr is bonded in a 6-coordinate geometry to six equivalent Cu and four equivalent In atoms. There are two shorter (2.99 Å) and four longer (3.02 Å) Pr–Cu bond lengths. All Pr–In bond lengths are 3.47 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Pr, one Cu, and two equivalent In atoms. The Cu–Cu bond length is 2.60 Å. Both Cu–In bond lengths are 3.13 Å. In is bonded to eight equivalent Pr and four equivalent Cu atoms to form a mixture of face and corner-sharing InPr8Cu4 cuboctahedra.
