Platinum nitride and osmium nitride may contain N 2 units, and as such should not be called nitrides. [11] [12] Nitrides of heavier members from group 11 and 12 are less stable than copper nitride (Cu 3 N) and zinc nitride (Zn 3 N 2): dry silver nitride (Ag 3 N) is a contact explosive which may detonate from the slightest touch, even a falling ...
