摘要：

Two new ternary nitrides, Sr3CrN3 and Ba3CrN3, were synthesised from the appropriate alkaline-earth-metal nitride and chromium metal or the chromium nitride, Cr2N, at high temperatures in sealed stainless-steel capsules. Structure determination from single-crystal X-ray data showed them to be isostructural in the hexagonal space group P-63/m, Z = 2, with lattice constants a = 7.724(2), c = 5.249(1) Angstrom for Sr3CrN3 and a = 8.201(2), c = 5.497(1) Angstrom for Ba3CrN3. The structures contain trigonal-planar [CrN3](6-) anions and either Sr2+ Or Ba2+ cations.
