Abstract: Single crystals of nonadecabarium nonaindium nonanitride, Ba₁₉In₉N₉, were synthesized by the Na flux method under N₂ pressure. The compound crystallizes in the monoclinic space group C2/m, with Z = 2. Polyanionic indium clusters [In₅]^5- and [In₈]^12- are surrounded by Ba²⁺ cations and are located in a flat cage built of linked nitrogen-centred NBa₆ octahedra. The structural formula is expressed as (Ba₃₈N₁₈)[In₅]₂[In₈].
