  • 摘要:The molybdenum bimetallic nitride MnMoN2has been synthesized by ammonolysis of the stoichiometric amorphous precursor, obtained by freeze drying o f aqueous solutio ns of the appropriate metal salts. The compound has been characterized by elemental analysis, energy-dispersive analysis of X-rays, X-ray diffraction, scanning electron microscopy, and thermogravimetry analysis under an oxygen atmosphere. MnMoN2crystallize in the hexago nal unit cell isostructural with β-MnWN2with a = 2.9226(6) ., c = 10.8563(8) ... It is stable under oxygen atmosphere up to 250 °C, the oxidation of the bulk reverting to the MnMoO4oxide being complete at 530 °C.
