Each of the three nitrogen centres bear formal charges.....


We gots #15+1# valence electrons to distribute over 3 centres, i.e. 8 electron pairs.....


And the 8 electron pairs are distributed, and VESPER would predict a linear anion. There is a formal NEGATIVE charge associated with the structure.
