An Unusually Stable Organic Radical (1 of 2)

Loading video...

Caption: This video shows a stick representation of the monoradical (7+) homo[2]catenane crystal structure. From this representation it is possible to get a sense of the interlocking nature of the two rings. Although these two rings are highly charged (4+ each), the two rings are connected indefinitely. This result leads to the stability of the radical electron in the molecule. 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.
