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

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.
