Abstract

A novel stable organic radical, 7,7-diphenyl-6,7-dihydro[1,2,5] thiadiazolo[3,4-f]quinoline-6-oxyl (1), forms a one-dimensional columnar structure consisting of slipped π-stacks, which is in contrast to dimer formation of the isoelectronic benzologue, 3,3-diphenyl-3,4-dihydrobenzo[f] quinoline-4-oxyl (2). Magnetic susceptibility of 1 obeyed an antiferromagnetic chain model with J = -47 cm-1, while 2 behaved as an isolated doublet spin state even in the dimer.
