SmPrFe4 is Cubic Laves-derived structured and crystallizes in the cubic F-43m space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Pr(1) and twelve equivalent Fe(1) atoms. Pr(1) is bonded in a 16-coordinate geometry to four equivalent Sm(1) and twelve equivalent Fe(1) atoms. Fe(1) is bonded to three equivalent Sm(1), three equivalent Pr(1), and six equivalent Fe(1) atoms to form a mixture of corner, edge, and face-sharing FePr3Sm3Fe6 cuboctahedra.
