A [Mn] wheel-of-wheels

A [Mn 18 ] wheel of wheels is obtained from the reaction of MnBr 2 ·4H 2 O and LH 3 in MeOH. The metallic skeleton reveals two asymmetric [Mn III 6 Mn II 2 ] square wheels connected into a larger wheel via two Mn II ions. Magnetic susceptibility and magnetisation data reveal competing exchange inter...

Zusammenfassung:A [Mn 18 ] wheel of wheels is obtained from the reaction of MnBr 2 ·4H 2 O and LH 3 in MeOH. The metallic skeleton reveals two asymmetric [Mn III 6 Mn II 2 ] square wheels connected into a larger wheel via two Mn II ions. Magnetic susceptibility and magnetisation data reveal competing exchange interactions, supported by computational studies. A [Mn 18 ] wheel of wheels is constructed from a simple reaction incorporating a triazatriol ligand.
