structural formula of adenine:

                 H
                  \
 H      N          N -- H
  \ //     \      /
   C        C -- C
    \      //     \\
     N -- C        N
           \      /
            N == C
                  \
                   H

See also: thymine, guanine, cytosine, and uracil.

I like it!
