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. %G English %2 https://univ-rennes.hal.science/hal-02397306/document %2 https://univ-rennes.hal.science/hal-02397306/file/Li%20et%20al-2019-Bromine-bridged%20Dy2%20single-molecule%20magnet%20magnetic-Revised.pdf %L hal-02397306 %U https://univ-rennes.hal.science/hal-02397306 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ SCR_OMC2012 %~ ISCR-OMC %~ ISCR-CTI %~ STATS-UR1 %~ UR1-SPM %~ GENCI %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ TEST-HALCNRS %~ UR1-MMS %~ TEST2-HALCNRS
