Ultralarge 3d/4f Coordination Wheels: From Carboxylate/Amino Alcohol-Supported {Fe₄Ln₂} to {Fe₁₈Ln₆} Rings.

ABSTRACT: A family of wheel-shaped charge-neutral heterometallic {Fe^III₄Ln^III₂}- and {Fe^III₁₈M^III₆}-type coordination clusters demonstrates the intricate interplay of solvent effects and structure-directing roles of semiflexible bridging ligands. The {Fe₄Ln₂}-type compounds [Fe₄Ln₂(O₂CCMe₃)₆(N₃)₄(Htea)₄]·2(EtOH), Ln = Dy (1a), Er (1b), Ho (1c); [Fe₄Tb₂(O₂CCMe₃)₆(N₃)₄(Htea)₄] (1d); [Fe₄Ln₂(O₂CCMe₃)₆(N₃)₄(Htea)₄]·2(CH₂Cl
