Materials Data on PrSmFe4 by Materials Project
SmPrFe4 is Cubic Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Sm is bonded in a 12-coordinate geometry to four equivalent Pr and twelve equivalent Fe atoms. All Sm–Pr bond lengths are 3.23 Å. All Sm–Fe bond lengths are 3.09 Å. Pr is bonded in a 12-coordinate geometry to four equivalent Sm and twelve equivalent Fe atoms. All Pr–Fe bond lengths are 3.09 Å. Fe is bonded to three equivalent Sm, three equivalent Pr, and six equivalent Fe atoms to form a mixture of corner, edge, and face-sharing FePr3Sm3Fe6 cuboctahedra. All Fe–Fe bond lengths are 2.64 Å.
