In this HOT article, Constantinos J. Milios and co-workers describe the synthesis, crystal structures and magnetic properties of (a hexanuclear and an octanuclear) manganese(III) complexes based on a new oxime ligand, 2-dihydroxy-2-phenylacetamidine. This is the first time that this ligand has been used for the synthesis of polynuclear complexes of any transition metal ion. Even though the hexanuclear complex resembles the previously reported [Mn6] clusters with salicyl-based oximes, the octanuclear complex presents a new structural type in Mn chemistry. Both complexes display moderate spin ground states (S = 3). The authors believe this new ligand is a promising candidate for a new extended family of manganese complexes with interesting magnetic properties and as impressive structures as its parent salicyl- or pyridyl-based oxime ligands.
