Abstract
- International audience; We report the first bromine-bridged dinuclear [Dy(CyPO)(μ-Br)(Br)]·2CH single-molecule magnet with an effective energy barrier of 684 K and magnetic hysteresis below 3 K. The asymmetric Dy centres present two unique stereoisomeric octahedral coordination environments depending on the cis/trans disposition of the CyPO ligands, leading to the orthogonality of the easy magnetic axes that annihilates the dipolar interactions.
