$Nitrogen(IV) dioxide..........$ $"Nitrogen(IV) dioxide.........."$

Explanation:

Or $dinitrogen tetroxide$ $"dinitrogen tetroxide"$ .

The Lewis structure of ${NO}_{2}$ $"NO"_2$ features a lone electron on the formally positive nitrogen centre, and this can rationalize the formation of $N_{2} O_{4}$ $"N"_2"O"_4$ , $dinitrogen tetroxide$ $"dinitrogen tetroxide"$ :

$2 (O = {. N}^{+} - O^{-}) ⇌ (^{-} O) (O =) N^{+} -^{+} N (= O) (O^{-})$ $2("O"=dot"N"^(+)-"O"^(-))rightleftharpoons(""^(-)"O")("O"=)"N"^(+)-""^(+)"N"(="O")("O"^-)$

The nitrogen radicals are conceived to couple to form a $N - N$ $"N"-"N"$ bond, in which both centres are still formal cations. What is the formal charge on the dimer?
