The ternary nitridotantalate, Sr2TaN3 has been synthesised via the solid state reaction of strontium subnitride, Sr2N, with either of the tantalum nitrides TaN or Ta3N5 in a sealed system under argon at elevated temperatures. The structure of Sr2TaN3 was determined for the first time by Rietveld refinement against powder X-ray diffraction data. The compound crystallises with the Ba2ZnO3 structure [monoclinic space group C2/c (No.15), a = 5.9835(1) Å, b = 11.2832(2) Å, c = 12.5814(2) Å, β = 92.26(1)°, V = 848.75(2) Å3, Z = 8] and is isostructural with other AII2MVN3 nitrides, Ba2TaN3, Sr(Ba)2NbN3 and Sr2VN3. The nitride contains infinite chains of corner-sharing TaN4 tetrahedral anions, 1[TaN2N2/2]4-, with Ta-N distances of 1.83-1.97 Å. Magnetic measurements are consistent with a nitridotantalate(V).
