Abstract
We report the synthesis of ternary transition metal nitrides of the formula MWN2 for M≡Mn, Co, Ni by reaction of the corresponding MWO4 with NH3 gas at 600-700 °C. MnWN2 is isostructural with the already-known FeWN2, crystallizing in a hexagonal structure (a=2.901(2), B=16.48(5) Å) related to LiMoN2, CoWN2 and NiWN2 (which are isostructural amongst themselves) adopt a different hexagonal structure with a smaller c parameter. While the Mn and Fe nitrides are semiconducting, the Co and Ni nitrides are semimetallic.
