Popis:	© The Royal Society of Chemistry 2015. The ability to modify the structure of nanoscopic assemblies in a controlled fashion is an important prerequisite for the creation of functional supramolecular systems. Here we describe a heterometallic Pt2Cu2 macrocycle which behaves as a molecular hinge. A square planar Pt(ii) complex with pendent 2 formylpyridine groups was synthesized and structurally characterized. Condensation of the complex with benzylamine followed by reaction with Cu(MeCN)4BF4 resulted in the formation of a rectangular Pt2Cu2 macrocycle. Upon chemical oxidation of the Cu centers the macrocycle folds up to adopt a butterfly like geometry in which the Pt centers approach each other. This process can be reversed by chemical reduction.
