#Cu_"3"N_"2"#

The easiest way of thinking about the combination of ions is by using the method I recall as being called , "the swap and drop"

So we have two ions,

#Cu^(2+)# and #N^(3-)#

now we swap the charge of each and drop, Note that the two ions have to be of opposite charge.

#Cu_"3"# and #N_2#

Now combine,

#Cu_"3"N_"2"#

This is the simplest formula.
