Answer:
The octet rule isn't all its cracked up to be. It works fine for some of the elements in the second period, but begins to come unglued for many others.
NNO does follow the octet rule, and has at least three resonance structures
N=N=O <−> N≡N−O <−> N−N≡O
Formal charges suggest that the one in the middle is most likely.

NICl2 (neutral) is an analogue of NCl3 where iodine has replaced one chlorine. It follows the octet rule.
