Hello, I need to write some chemical strucutures in LaTeX and dont know, what is the best tools to do it. The structures are crown ether and cryptands. Yes, and I am unexperienced. 1) What would be the way to write a [18]crown-6 (http://en.wikipedia.org/wiki/Crown_ether) structure formula with PPCHTEX? 2) Is there any kind of repository, where I can take common structures and/or adapt these to the required structures? Regards, Helge
