Bis(β-diketonate) ligands for the synthesis of bimetallic complexes of TiIII, VIII, MnIII and FeIII with a triple-helix structure

Addition of the bis(β-diketone) ligand L [L = 1,3-bis(3-phenyl-3-oxopropanoyl)benzene] to a suitable source of M III ions (M = Ti, V, Mn, Fe) in a L:M = 3:2 ratio gives the dinuclear products [M 2 L 3 ], which have a triple-helical structure.
