Zinc nitride is an inorganic chemical compound of zinc from the group of nitrides . It was first synthesized in 1940 by R. Juza and H. Hahn.

Extraction and presentation

Zinc nitride can be obtained by reacting zinc or zinc oxide with ammonia .

{\ displaystyle \ mathrm {3 \ ZnO + 2 \ NH_ {3} \ longrightarrow Zn_ {3} N_ {2} +3 \ H_ {2} O}}

It is also possible to manufacture by reacting zinc with nitrogen at 600 ° C.

properties

Zinc nitride is a blackish-gray solid that is largely stable in air. It has a cubic crystal structure. This is isostructural to that of magnesium nitride , calcium nitride and cadmium nitride, an anti- bixbyite structure with the space group Ia 3 (space group number 206) and the lattice parameter a = 9.7691 Å . The crystal structure is a derivative of that of calcium fluoride , with nitrogen and zinc atoms taking the position of calcium and three quarters of the fluorine positions. In this cubic structure, zinc atoms occupy the tetrahedral gaps of an approximately cubic packed arrangement of nitrogen atoms. Template: room group / 206
