The crystal structure of Na5Ba3N was determined from a single crystal grown by a diffusion limited process (Pnma, a = 11.882(2) Å,b = 7.049(1) A, c = 17.792(4) A, Z = 4, R = 0.063). The structure contains Ba3N chains nearly identical with those found in NaBa3N. The structure can be explained in terms of strong Ba—N intrachain ionic bonding and weak Ba—Na metallic bonding separating the chains. Na5Ba3N is a common impurity phase in Na—Ba alloys, which has probably exacerbated the difficulties in determining Na—Ba phase equilibria. Na5Ba3N has the structural characteristics of a one-dimensional void metal.
