No, EAN of Fein brown ring complex is not independent of charge on NO.
EAN= Atomic number of metal - Oxidation No of metal + 2*Coordination no.
= 26 – 1 + 2*10
= 35 (which is not equal to next inert gas atomic number)
NO+ in this complex is 1 electron donor unlike the general 3 electron donator.
= 26 – 1 + 2*10 + 1 (contribution from NO+)
= 36
This is achieved due to contribution of electrons from NO+.
