Cadmium nitride is an inorganic chemical compound of cadmium from the group of nitrides .

Extraction and presentation

Cadmium nitride can be obtained by thermal decomposition of cadmium amide at 180 ° C.

{\ displaystyle \ mathrm {3 \ Cd (NH_ {2}) _ {2} \ longrightarrow Cd_ {3} N_ {2} +4 \ NH_ {3}}}

It can also be obtained by thermal decomposition of cadmium azide at 210 ° C.

properties

Cadmium nitride is a black solid that decomposes on contact with air and moisture. Explosive decomposition occurs with diluted acids and alkalis. The compound has a cubic crystal structure of the anti- manganese (III) oxide type (a = 1079 pm).
