Materials Data on FeNiPt2 by Materials Project
Pt2FeNi crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Fe2+ 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 Fe2+, four equivalent Pt2-, and four equivalent Ni2+ atoms to form a mixture of distorted face, edge, and corner-sharing PtFe4Ni4Pt4 cuboctahedra. All Pt–Pt bond lengths are 2.74 Å. All Pt–Ni bond lengths are 2.67 Å. Ni2+ is bonded in a body-centered cubic geometry to eight equivalent Pt2- atoms.
