Here we present three structurally diverse clusters stabilised by the same macrocyclic polyphenol; t-butylcalixarene. This work demonstrates the range of conformations the flexible ligand is capable of adopting, highlighting its versatility in metal coordination. In addition, a Ti complex displays activity for the ring-opening polymerisation of lactide.
