In this study, the importance of anion-pi interactions in four-membered rings has been evidenced. Two kinds of rings have been found to be suitable for participation in anion-pi interactions: first, in different salts of cyclobuten-1,2-dione derivatives and, second, in eta(4)-Cyclobutadiene complexes with transition metals.
