What sort of information do you want / need? Perhaps http://en.wikipedia.org/w/index.php?title=Special:Cite&page=Crown_ether&id=308493821 is a good place to start?

Thank you,that is really a good place to start,and i need more than that after the start .
Almost the articles or books in the internet about crown ether are not free,so i can not read full version,i have looked for so many times but only found a few!I hope to get something about it!

It is common for articles in WIKI to have references and links at bottom that may give sources you can read for better citations.
