Abstract

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.
