Formation of a One-Dimensional Stacking Structure of π-Conjugated Nitroxyl Radical Bearing a 1,2,5-Thiadiazole Ring and Its Magnetic Property
Source abstract
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.
