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.
