The reaction between barium and nitrogen in liquid sodium: resistivity studies

Synthesis, Structure, and Magnetic Properties of Sr39Co12N31

“…However, in a melt containing sodium and even a few mole percent of an alkaline earth metal, the solubility of nitrogen is increased to approximately 1 mol% (41, 42). Addison et al suggested that a Ba N cluster is the dissolution species based on precipitation studies in the Na-Ba-N system (43). However, crystallographic information provided by Simon et al on subnitrides in the sodium-alkaline earth system indicates that the most probable dissolution species is a nitrogen-centered, A N, octahedral species, where A"Ca, Sr, and Ba (44)(45)(46)(47)(48).…”
