Materials Data on MnFePt2 by Materials Project
MnFePt2 is Tetraauricupride-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Mn2+ is bonded in a distorted body-centered cubic geometry to eight equivalent Pt2- atoms. All Mn–Pt bond lengths are 2.64 Å. Fe2+ is bonded in a distorted body-centered cubic geometry to eight equivalent Pt2- atoms. All Fe–Pt bond lengths are 2.65 Å. Pt2- is bonded to four equivalent Mn2+, four equivalent Fe2+, and four equivalent Pt2- atoms to form a mixture of distorted face, edge, and corner-sharing PtMn4Fe4Pt4 cuboctahedra. All Pt–Pt bond lengths are 2.66 Å.
