摘要：

Ca2[FeN2] (monocl., C2/m (No. 12); a = 1093.0(2) pm, b = 496.0(1) pm, c = 684.4(1) pm, beta = 121.09(1)-degrees; Z = 4) and Sr2[FeN2] (tricl., P1BAR (No.2); a = 653.8(1) pm, b = 869.0(2) pm, c = 893.2(2) pm, alpha = 90.22(2)-degrees, beta = 109.45(1)-degrees, gamma = 102.30(1)-degrees; Z = 5) were prepared by reaction of mixtures Ca3N2/Fe (Sr2N/Fe) with nitrogen (1 atm) at 850-degrees-C. The crystal structure of Ca2[FeN2] contains isolated planar anions [Fe2N4]8-; in the crystal structure of Sr2[FeN2] planar [Fe2N4]8- units are present as well as linear anions [FeN2]4-.
