  Tellurium nitride describes chemical compounds of Te containing $N^{3−}.$ Efforts have been made toward the binary nitrides but the results are inconclusive and it appears that such materials are unstable. Still unconfirmed is $Te_4N_4,$ which would be an analogue of tetraselenium tetranitride $(Se_4N_4)$ and tetrasulfur tetranitride $(S_4N_4).$ It has long been known that ammonia reacts with tellurium tetrachloride, which is similar to the method of synthesis of $S_4N_4.$ The reaction of $TeCl_4$ with a THF solution of $N(SiMe_3)_3$ gives a well-defined tellurium nitride $[Te_6N_8(TeCl_2)_4(THF)_4].$
