Tin(IV) nitride
Tin(IV) nitride, Sn3N4, was first isolated in 1999 from the reaction of SnI4 with KNH2 in liquid NH3 at 243K followed by annealing the solid product at 573 K. Sn3N4 adopts a spinel-type structure, related to that of γ-Si3N4 described above. Tin(IV) nitride is the first nitride spinel that is stable under ambient conditions.
