Crystal clear: The title macrocycle was constructed by a nickel-mediated shotgun macrocyclization. The X-ray crystallographic structure of 12CPP revealed a circular structure incorporating two cyclohexane molecules within the ring. The 12CPP molecules were also found to crystallize into tubular and herringbone structures.
Segawa et al. (2011) studied this question.
