Caption: This video shows a spacefilling representation of the monoradical (7+) homo[2]catenane crystal structure. From this representation it is possible to get a sense of how tightly bound these two rings are where there is very little free space between each ring. This video relates to a paper that appeared in Jan. 25, 2013, issue of Science, published by AAAS. The paper, by Jonathan C. Barnes at Northwestern University in Evanston, IL, and colleagues was titled, "A Radically Configurable Six-State Compound."
