Abstract
Sr3[MnN3] (hexag. P 63/m (Nr. 176); a = 764.2(1) pm, c = 529.8(1) pm; Z = 2) and Ba3[MnN3] (hexag. P 63/m (Nr. 176); a = 805.0(2) pm, c = 5 58.6(1) pm; Z = 2) are isotypes of the Ba3[FeN3] crystal structure and contain trigonal-planar anions [MnN3]6- with D3h-SyMMetry (Mn-N: 174.1(13) pm/173.7(12) pm). The compounds were prepared by reaction of mixtures of Li, Sr/Ba and Mn (molar ratio 2: 1: 1) in tungsten crucibles with nitrogen (I atm) at 850-degrees-C.
