An elegant way would be to use pstricks or xypic macros. However this
can be accomplished by an array construct as given below:
\arraycolsep2pt
\def\hr{\rule[.5ex]{2em}{.2pt}}
% define a horizonal rule
\def\vr{\vrule depth -.5ex height 10pt width .2pt}
% define a vertical rule
$\begin{array}{lllll}
\vline\hr &\multicolumn{3}{l}{\mbox{Compounds}}\\
\vr\hr &\multicolumn{3}{l}{\mbox{Compounds}}\\
&\:\:\vline\hr &\multicolumn{3}{l}{\mbox{Radical}}\\
&\:\:\vr\hr &\multicolumn{3}{l}{\mbox{Radical}}\\
&&&\:\:\vr\ldots\ldots &\mbox{Atoms}
\end{array}$
