Popis:	YFe 12-x Mo x (x=1 and 3) and full-charged nitrides were prepared. Neutron-ponuder-diffraction experiments were performed at 10 K and room temperature on both the host compounds and their nitrides. The Rietveld technique was used for data analysis. Mo was found to reside mainly on the 8i site in the tetragonal ThMn 12 structure (space group I4/mmm), with a small fraction on the 8f site. The nitrides retain the crystallographic symmetry of the host compounds. Nitrogen atoms are located on the 2b site with nearly 100% occupancy
