Abstract
We first reported a macrocyclic trisaloph ligand composed of three N2O2 coordination sites. When the three N2O2 ligation units of the trisaloph analogues bind to metal ions, their homo and hetero multi-nuclear complexes were formed due to ligation on the N2O2 and central O6 sites. Two types of zinc carboxylates, i.e., acetate and methacrylate, have been reported for the zinc cluster complexes of the trisaloph ligands, and the structures of these complexes resemble each other. Thus, we intended to change the bridging anion to construct a different cluster structure. We now report the synthesis of a trisaloph hexanuclear complex with a more bulky ligand than the MeCO2 ligand and also demonstrate its different nuclearity and unique dynamic structural behavior of the multinuclear complex in solution.
