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

 

\begin{figure}[H] \subfigure[\ch{C6H4(CN)2}]{
\scriptsize
\chemfig{*6(-=(-CN)-(-CN)=-=)} % phthalonitrile
}
\subfigure[\ch{CuC32N8H16}]{
\scriptsize
\chemfig{N?(=[::+72]*5(-N-(=N-[::-72]*5(=[,,,1]N-[,,1](=N-[::-36]*5(-N-(-N=[::-72]*5(-N=[,,1]?-*6(-=-=-=)–))=*6(-=-=–)-=))-*6(-=-=–)=-))-*6(-=-=-=)–))-[,,,,draw=none]-[,,,,draw=none]Cu(-[:55,,,,dash pattern=on 2pt off 1pt])(-[:-55])(-[:125])(-[:-125,,,,dash pattern=on 2pt off 1pt])}
}
\caption{The phthalonitrile in (a) is used to make copper phthalocyanine in (b).}
\end{figure}

Here is the output of this figure:
