摘要：

Red transparent single crystals of Ba-9[NbN4](2)O[CN2] were synthesised by the reaction of BaO coated Ba metal, C and Nb powder in arc-welded Nb ampoules at 1300 K. The title compound was characterised by X-ray single crystal diffraction (P (1) over bar, a = 799.05(2), b = 962.61(2) and c = 1264.38(4) pm; alpha = 75.859(1), beta = 85.745(1) and gamma = 87.8621(8)degrees; Z = 2) and Raman spectroscopy (nu(sym) = 1234 and delta = 632/658/668 cm(-1)). It now seems likely that a nitride-azide compound we previously reported, Bag [NbN4](2)N[N-3], does not exist, but is in fact the title compound.
