Abstract
The new lithium nitridotantalate(V), Li4[TaN3], was prepared by reaction of Li15[CrN4]2N with the wall of a welded Ta ampoule in the presence of metallic Li at 1470 K. Li4[TaN3] forms colourless single crystals (platelets, space group Ibca, No. 73, a = 491.85(4) pm, b = 973.59(6) pm, c = 1415.0(1) pm, Z = 8, R1 = 0.0288). The crystal structure is described as Li2O superstructure with ordered occupation of the tetrahedral sites by Li and Ta. The resulting arrangement leads to infinite chains ∞1[TaN2N2/24- running along [100].
