Abstract

Two new hexanuclear symmetric dysprosium wheels, namely, [Dy ₆(L₁)₆(L′)₆(OCH ₃)₆(2CH₃OH)] and [Dy₆(L ₂)₆(L′)₆(OCH₃) ₆(2CH₃OH)] (L₁H = pivalic acid and L ₂H = 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.
