The new layered ternary transition metal nitride (Fe{sub 0.8}Mo{sub 0.2})MoN{sub 2} has been synthesized in a single-step reaction by the ammonolysis of the transition-metal oxide, Fe{sub 2}(MoO{sub 4}){sub 3}. Powder X-ray diffraction data were collected and the structure was refined using the Rietveld method (P31c, a = 2.8562 {Angstrom}, c = 10.9997 {Angstrom} ). The structure consists of alternating layers of MN{sub 6} (M = Mo:Fe (1:4)) octahedra and M{sup {prime}}N{sub 6} (M{sup {prime}} = Mo) trigonal prisms. The magnetic susceptibility data display a maximum at 20 K. Four-probe conductivity measurements indicate poor metallic conductivity with a very small temperature dependence. 46 refs., 5 figs., 3 tabs.
