چکیده
The easy-to-prepare Nb(V) aryloxide complex [(ArO)2Nb(μ-Cl)Cl2]2 (OAr = 2,6-bis(diphenylmethyl)-4-tert-butylphenoxide) is a precursor to both Nb(IV), [trans-(ArO)2NbCl2(THF)2], and Nb(III), K3[(ArO)4Nb2(μ-Cl)3Cl2], molecules. The Nb(IV) and (V) complexes readily split atmospheric nitrogen at room temperature and 1 atmosphere, under reducing conditions, to produce the low-coordinate nitride dimer [(ArO)2Nb(μ-N)]2 and its radical anion, K[(ArO)2Nb(μ-N)]2.

Nitrogen Partial Pressure of Stoichiometric and Nonstoichiometric Titanium, Vanadium and Niobium Nitrides and Carbonitrides
A method is proposed for calculating the nitrogen equilibrium partial pressure pN2 of stoichiometric and nonstoichiometric nitrides MNy and carbonitrides MCyN1ÿy (M Ti, Zr, Hf, V, Nb, Ta) with B1(NaCl)-type structure. Analytic forms are derived for the composition, nonstoichiometry, and temperature dependences of the nitrogen partial pressure of the afore-mentioned compounds. The partial pres...
متن کاملMonolithic Gyroidal Mesoporous Mixed Titanium–Niobium Nitrides
Mesoporous transition metal nitrides are interesting materials for energy conversion and storage applications due to their conductivity and durability. We present ordered mixed titanium-niobium (8:2, 1:1) nitrides with gyroidal network structures synthesized from triblock terpolymer structure-directed mixed oxides. The materials retain both macroscopic integrity and mesoscale ordering despite h...
متن کاملEELS study of niobium carbo-nitride nano-precipitates in ferrite.
Micro-alloying steels allow higher strength to be achieved, with lower carbon contents, without a loss in toughness, weldability or formability through the generation of a fine ferrite grain size with additional strengthening being provided by the fine scale precipitation of complex carbo-nitride particles. Niobium is reported to be the most efficient micro-alloying element to achieve refinemen...

Structural and magnetic properties of the GdFe12_~MOx compounds having the ThMn12 type of structure were studied. Rare-earth nitrides of the composition GdFe 12-x MOx N y were prepared by the reaction of GdFe12_x MOx with nitrogen gas at 475°C. The crystal structure and lattice constants have been determined for all compounds. The lattice expansion of the nitrogenated compounds is mainly along ...
