A new niobium oxynitride Nb 2 N 0.88 O 0.12 has been synthesized by reducing Nb 2 O 5 in a stream of H 2 gas containing 0.07% N 2 at 10803C for 5 weeks. The compound crystallizes in a hexagonal system with space group P3 1m, and Z β«Ψβ¬ 3. The lattice parameters are a β«Ψβ¬ 5.2916$0.0001 A s and c β«Ψβ¬ 4
## Abstract The copperβdeficient title compound La~3~Cu~5βx~Te~7~ (x = 0.07, 0.14, 0.12) is synthesized from the elements (graphite crucible in a sealed silica tube, 1073 K, 14 d) and characterized by single crystal XRD, electrical measurements, and LMTO band structure calculations.
A new compound was prepared by heating \(\mathrm{La}_{2} \mathrm{O}_{3}\) in the presence of carbon under an ammonia atmosphere. The chemical formula of the compound was determined to be \(\mathrm{La}_{2} \mathrm{O}_{2} \mathrm{CN}_{2}\) both from results of CHN analysis and weight change upon oxida
