I'm not sure what you're asking. Justin suggested a good approach for generating a "solvent box" of nitrogen.
Implementing an MD model of dinitrogen in a .top/.itp file is about 5 minutes' work with a text editor if you already have suitable parameters and an existing .top to act as a template. (One [atomtype], one [bondtype], one [moleculetype], two [atoms], one [bonds]. Then a [molecules] section. Finished.) If you don't have parameters already, search the literature in the first instance.
