In NO2 structure there is an unpaired electron left on Nitrogen atom, so it is reactive it dimerises to pair up its electron and gains stability as N2O2.

No2 contain odd number of valence electrons. It behaves as a typical odd molecule.On dimerisation,
it is converted to stable N2O4 molecule with even number of electrons.
