Using the ChemFig package in LaTeX, you can generate the Phthalocyanine molecule as follows,

the source code is available on GitHub/ThomasGredig.

 

\chemfig{

  N?[a]=[::+63]*5(-N?[b]=(-N=[::-54]*5(

        -N?[c]=( -N=[::-54]*5(-N?[d]=(

              -N=[::-54]*5(-N(-[::-54,1.5]Fe?[b,,dotted]?[c]?[d,,dotted])

                =[,,1]?[a]-(*6(=-=-=-))-- )  )-(*6(=-=-=-))-- )  )

        -(*6(=-=-=-))-- )  ) -(*6(=-=-=-))-- )

}

Here is the output of this figure:
