title: Structures and magnetic properties of two analogous Dy6 wheels with electron-donation and -withdrawal effects.
abstract: Two new hexanuclear symmetric dysprosium wheels, namely, [Dy6(L1)6(L')6(OCH3)6(2CH3OH)] and [Dy6(L2)6(L')6(OCH3)6(2CH3OH)] (L1H = pivalic acid and L2H = 3,5-dinitrobenzoic acid, L'H= 2,6-dimethoxyphenol) were isolated employing a mixed-ligand strategy. The strategic introduction of two different auxiliary groups with diverse steric effects and electrostatic actions affect the magnetic coupling and local anisotropy of Dy(III) ion, therefore exhibiting dissimilar magnetic behaviors.
