The neutron diffraction powder patterns of Pr₂Fe₁₇ and Pr₂Fe₁₇N_2.6 have been measured at 295 K and refined within the Th₂Zn₁₇ structure type to give the structural changes which occur upon nitrogenation; changes which include a 6.4% expansion of the unit cell volume. The Mössbauer spectra of Pr ₂Fe₁₇ and Pr₂Fe₁₇N_2.6 have been measured between 85 and 295 K and analyzed with a model which is based on the Wigner-Seitz cell environment of each iron site, the basal orientation of the magnetization, and …
