Abstract

A new flexible bis(amidine) ligand featuring two additional N-donor groups incorporates a defined [Cu^IMesCu₂^I]²⁺ fragment from mesitylcopper into a triangular cluster with a reactive organometallic coordination site. Subtle changes to the reaction protocol result in the formation of an intertwined tetracuprous arrangement that adopts the shape of a Möbius strip.
