Abstract

A couple of TEMPO-substituted anthraquinone isomers showed marked difference regarding solvating properties and the resulting magnetic behavior: without obstruction an isomer includes solvent molecules as benzene or acetonitrile to form crystals exhibiting different intermolecular magnetic interactions, while another isomer gives solvent-free crystals showing singlet-triplet behavior.
