An elegant way would be to use pstricks or xypic macros.  However this
can be accomplished by an array construct as given below:

% define a horizonal rule

\def\vr{\vrule depth -.5ex height 10pt width .2pt}
% define a vertical rule

\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}
