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.
