A new stable compound in the Nd--Fe system has been identified as Nd{sub 5}Fe{sub 17}. The crystal structure belongs to the hexagonal space group P6{sub 3}/mcm, with {ital a}=2.0214(8) nm and {ital c}=1.2329(8) nm, and with 12 formula units per unit cell. This compound is a ferromagnet with {ital T}{sub {ital c}} = 503 K and magnetization 162 emu/g at 4.2 K. Moessbauer spectra have been measured and fitted with five Fe sites, yielding an average {ital B}{sub eff}=26.5 T at room temperature, from which an average Fe moment of 1.83 Bohr magnetons is deduced. X-ray powder diagrams from magnetically aligned samples suggest basal anisotropy.
