Abstract
The crystal of 9,9-dipropyl-9,10-dihydroacridin-10-yloxyl exhibited a posit ive Weiss constant (+0.77 K) due to a 3-D network of ferromagnetic interact ions. The crystal of 6,6-bis(p-ethylphenyl)-5,6-dihydrophenanthridin-5-ylox yl was revealed to possess a ferromagnetic dimer structure with 2J/k(B)= +3 .5 K. Several bisbiphenylyl nib-oxide radicals showed ferromagnetic interac tion.
