The surface dictates : The metallodipeptide complex [{Zn(Dpg‐Tyr‐O)} n ] n + (Dpg=dipicolylglycyl, Tyr=tyrosine) is a right‐handed homochiral helical coordination polymer. Depending on the local structure of a pyrolytic graphite surface, it aggregates to form double‐helical plaits (left) or two‐dimensional assemblies of linearly stretched strands (right). The strands represent the first step in the formation of a three‐dimensional crystal.
