Zinknitrid is an inorganic chemical compound of zinc, selected from the group of nitrides. It was first synthesized in 1940 by R. Juza and H. Hahn.
Production and representation
Zinknitrid can be obtained by reaction of zinc oxide or zinc oxide with ammonia.
Another option is the production by the reaction of zinc with nitrogen at 600 ° C.
Properties
Zinknitrid is a black and gray, air largely resistant solid. It has a cubic crystal structure. This is isostructural to that of magnesium nitride, calcium nitride and Cadmiumnitrid an anti - bixbyite structure with space group Ia3 and the lattice parameters a = 9.7691 Å. The crystal structure is a derivative of calcium fluoride, wherein nitrogen and zinc atoms occupy the position of the calcium and three quarters of the fluorine - positions. In this cubic structure of zinc atoms occupy the tetrahedral holes about a cubic packed arrangement of nitrogen atoms.
