Nagashima, Hideaki; Inoue, Hidenari; Yoshioka, Naoki published the artcile< Synthesis, solution ESR spectra, and solid-state magnetic property of thieno[3,4-d]imidazol-2-yl nitronyl nitroxide>, Quality Control of 6136-93-2, the main research area is ESR spectrum solid state magnetic property thienimidazolyl nitronyl nitroxide.
2-(Thieno[3,4-d]imidazol-2-yl)-1,3-dihydro-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (2) was designed and synthesized. Compound 2 was stable in a solid state but unstable in organic solvents. Solution ESR spectra showed that small spin densities locate on the four Me groups and the thieno[3,4-d]imidazole ring, though most of spin densities localized on the ONCNO moiety. Magnetic susceptibility measurement showed that antiferromagnetic interaction is dominant which could be fitted to the Bonner-Fisher model with J=-8.8 cm-1.
Polyhedron published new progress about Antiferromagnetism (interaction). 6136-93-2 belongs to class nitriles-buliding-blocks, and the molecular formula is C6H11NO2, Quality Control of 6136-93-2.
