Abstract

Several years ago we reported the results of a detailed study of the reaction of nitrogen with solutions of alkaline earth metals in liquid sodium [1–4]. For the Na-Ba-N system, resistivity [1] and solubility [2] studies of the solutions coupled with X-ray powder diffraction studies of the solid products [3] indicated that an initial solution process is followed by the precipitation of Ba2N which, in the presence of excess nitrogen, reacts further to form Ba3N2- Since the extent of the solution process is determined solely by the amount of barium dissolved in the liquid sodium, precipitation commencing at a Ba:N ratio of 4:1, it has been suggested [5] that the nitrogen, which is effectively insoluble in liquid sodium [6], is solvated by the barium forming a soluble “Ba4N” species. The reaction sequence, which can be summarised as follows.
