Dimers of the adenine molecule.

(a–e): dimers I to V; Furukawa et al.18 and Shinoda et al.19 used these dimers to develop a model for single- and double-chains made of adenine on Cu(111); (f) A6A6: a dimer that could potentially be a link between the two single-chains in the adenine double-chain structures termed as DCH2 and DCH3 by Shinoda et al.19.
