A supramolecular assembly of {Fe10} molecular wheels with tubular structures

Abstract

A 3-D supramolecular assembly of {Fe₁₀} molecular wheels, [Fe(CH₃O)₂(O₂CCH₂O–Ph)]₁₀·6H₂O (1) with tubular structure was successfully prepared by a novel approach of simple modification of the building blocks for making symmetric clusters, Fe₁₀. The diameter of the tubes is approximately 8.9 Å. Meanwhile, this tubular structure as the host traps hexameric clusters of water and the magnetic property of complex 1 shows that antiferromagnetic interactions exist between the high–spin iron(III) ions (S = 5/2) with J = 5.36 cm⁻¹ and g = 2.03.
