Stimulated by the concept of the possibility of a polarizable N3− ion and the potentiality of its being a fast Li-ionic conductor, lithium nitride, Li3N, has been, and still is, the subject of broad interdisciplinary investigations. These form an excellent example for modern solid state research. This paper will describe this situation and review the present state of this fast developing field.
The tellurium subhalides represent a group of recently discovered compounds which have been investigated by the methods of solid-state and structural chemistry. Because of their high tellurium content and their crystal structures containing homonuclear tellurium connections they have attained significance as “modified tellurium structures”. As a consequence, tellurium subhalides have been the subject...
