摘要：

(Li1-xNix)Li4Sr2N3 (x = 0.22) was prepared by the reaction of lithium and strontium (molar ratio 2:1) in a nickel crucible with nitrogen at 900-degrees-C, followed by cooling to room temperature (20-degrees-C h-1). The crystal structure was determined by single-crystal X-ray diffraction (Cmmm; a = 376.7(l) pm, b = 2073.9(3) pm, c = 391.6(l) pm; z = 4). Infinite two-dimensional fragments of the Li4SrN2 structure and the LiSrN structure alternate along the [010] direction and are condensed via common strontium sites. Strontium is tetrahedrally coordinated by nitrogen. The Li-N frameworks show close structural relationships to sections of the Li3N-type structure.
