If PPCHTeX is capable of drawing your formulas. I tried it, and apart from 
complicated notation it can not draw seven rings, and you need "work arounds" 
for certain bond angles, and there were other things either very complicated 
to code or not at all. There seems to be no big user community of PPCHTeX and 
no development.

Have a look into the PPCHTEeX-manual and see if it covers all your needs.

True, and also XyMTeX lacks a lot of possibilities - apart from seven rings 
many bicyclo-compounds are not possible, if I remember right. Additionally, 
it is not possible to colorize bonds and atoms or to make them bold etc. 
(this is possible with PPCHTeX).

Then there is ochem by Ingo Klöckl, perhaps the most powerful chemistry 
solution in terms of possible compounds - but only for LaTeX, and again with 
a very peculiar notation and a steep learning curve. Colorization of bonds 
only with PostScript-editing.

Finally there is streetex by Igor Strokov - again for LaTeX, more powerful in 
terms of possible compounds than PPCHTeX or XyMTeX and much easier (more 
intuitive) to use. However, as with XyMTeX it is not possible to colorize 
bonds and atoms or to make them bold etc.

Recent versions of Cambrigde Soft ChemDraw can produce very nice output in 
various formats. Additionally, ChemDraw has the feature IUPAC name to 
structure - this is very handy, and no TeX-solution has that.
