Crystal architectures of organic molecular-based magnets

The crystal architectures of molecular materials play deciding roles when i t comes to the determination of magnetic properties. In turn, the build-up of these arrangements is shown to depend on the molecular features present in the compounds employed. An analysis of the molecular and supramolecular aspects of the alpha-nitronyl aminoxyl radicals is presented, and a critica l appraisal of the state of the art in interpretation of magnetic interacti ons and ability to crystallize predetermined relative orientations between radicals is presented.
