Abstract
The novel 18-metallacrown-6 complex, with the formula of [Mn6(C11H11N2O3)6(CH3CH2OH)6]·3C3H7NO·2CH3CH2OH (1) (pmshz = N-propanoyl-3-methyl-salicylhydrazide), has been prepared and characterized. The self-assembled, manganese complex assumes a nearly planar cyclic structure with an [Mn–N–N]6 backbone. Due to the coordination, the ligand enforces the stereochemistry of the Mn3+ ions as a propeller shape with alternating …ΔΛΔΛ… configurations. The magnetic properties of the metallacrown molecule are characterized by a weak antiferromagnetic exchange interaction between the Mn3+ ion spins with S = 2 in the cyclic system.
