Abstract Red transparent single crystals of Ba9[NbN4]2O[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 (P1̅ , a = 799.05(2), b = 962.61(2) and c = 1264.38(4) pm; α = 75.859(1), β = 85.745(1) and γ = 87.8621(8)°; Z = 2) and Raman spectroscopy (νsym = 1234 and δ = 632/658/668 cm−1). It now seems likely that a nitride-azide compound we previously reported, Ba9[NbN4]2N[N3], does not exist, but is in fact the title compound.
