Copper (I) nitride is an inorganic chemical compound of copper from the group of nitrides .

Extraction and presentation

Copper (I) nitride can be obtained by reacting copper (II) fluoride with ammonia .

properties

Copper (I) nitride is a dark green solid that is stable in air at room temperature. At 400 ° C, oxygen is used to oxidize with intense glowing. In a vacuum , spontaneous decomposition takes place at around 450 ° C. The compound is soluble in dilute mineral acids and concentrated hydrochloric acid with the formation of the corresponding ammonium salt and partial formation of copper. Stormy decomposition occurs on contact with concentrated sulfuric and nitric acid . Copper (I) nitride has a cubic crystal structure (anti- rhenium trioxide structure) with the space group Pm 3 m (space group no. 221) . The lattice parameter is a = 381 pm.
