Trying to add interwiki :en:Molecular oxygen, it is recognized by the autocomplete; but when submit returns the error «Edit not allowed: El enlace del sitio [[enwiki:Oxygen]] ya es usado por el elemento [[Q327]].»
The problem is that in the English Wikipedia, the article of the element and the article of the molecule are merged onto one single article, and the last one redirects to the first one.
In my experience, this is not an exception nor it's limited to chemistry. Often I found two articles on one wikipedia merged on another wiki.
