The introduction of group 10 metals into the hypothetical composition Fe2Mo3N allows the isolation of the solid solutions Fe2-xMxMo3N (M = Ni, Pd, Pt), which crystallize with the filled β-manganese structure (space group P4132, a ≈ 6.7 Å). These materials display ferromagnetism with the Curie temperature and saturation magnetization being dependent on the iron content; Fe1.25Mo0.75Mo3N shows the highest ordering temperature in each series (maximized at Tc = 225 K for M = Pt) and the highest magnetization is always observed for x = 0.5 (maximized at 2.44 μB per formula unit for M = Pd). © 2005 American Chemical Society.
