Materials Data on FeCuPt2 by Materials Project
FePt2Cu crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Fe3+ is bonded in a body-centered cubic geometry to eight equivalent Pt2- atoms. All Fe–Pt bond lengths are 2.67 Å. Pt2- is bonded to four equivalent Fe3+ and four equivalent Cu1+ atoms to form a mixture of distorted corner, edge, and face-sharing PtFe4Cu4 cuboctahedra. All Pt–Cu bond lengths are 2.67 Å. Cu1+ is bonded in a body-centered cubic geometry to eight equivalent Pt2- atoms.
