Abstract:
Di‐ n ‐butyltin dichloride ( n Bu 2 SnCl 2 ) was treated with the potassium salt of cis ‐1,4‐cyclohexanedicarboxylate ( cis ‐1,4‐chdcaK 2 ) to give di‐ n ‐butyltin cis ‐1,4‐cyclohexanedicarboxylate. In the solid state two supramolecular isomers coexist within the same crystal lattice, the 36‐membered macrocyclic tetranuclear complex [{ n Bu 2 Sn( cis ‐1,4‐chdca)} 4 ] and the analogous polymeric form [{ n Bu 2 Sn( cis ‐1,4‐chdca)} n ]. In solution, fast (on the NMR time scale) dynamic equilibria were detected. The supramolecular arrangement in the solid state consists of alternating macrocycle and polymer ribbons with different patterns o f intermolecular Sn ··· O interactions that give rise to a total of four different types of supramolecular macrocyclic assemblies. They probably resemble local environments in the liquid phase and allow to propose a plausible mechanistic pathway for the ring‐chain rearrangement dynamics during which the macrocycle molecules are transformed into other macrocyclic and polymeric molecules.(© Wiley‐VCH Verlag GmbH & Co.
