Sasiadek, Wojciech; Bryndal, Iwona; Lis, Tadeusz; Wandas, Maria; Hanuza, Jerzy published the artcile< Synthesis and physicochemical properties of the methyl-nitro-pyridine-disulfide: X-ray, NMR, electron absorption and emission, IR and Raman studies and quantum chemical calculations>, Computed Properties of 19346-45-3, the main research area is methyl nitro pyridine disulfide preparation crystal structure IR NMR.

The methyl-nitro-pyridine-disulfide derivative [2,2′-disulfanodiylbis(6-metyl-3-nitropyridine)] was synthesized and characterized by means of structural and spectroscopic measurements. On the basis of X-ray diffraction studies, it was found that the studied compound crystallizes in the centrosym. monoclinic space group P21/n (Z = 2). The disulfide C-S-S-C bridge links two identical fragments formed by pyridine rings substituted with Me and nitro groups. Such a structure was confirmed by 1H and 13C NMR studies as well as IR, Raman, UV-VIS and emission spectra. Quantum chem. DFT calculations were applied in the anal. of the obtained results. The vibrational characteristics were reported and dynamical properties of this moiety were discussed. A full set of the normal modes characteristic for the disulfide bridge was identified and assigned to the resp. IR and Raman bands. The results of structural and spectroscopic studies were used to find the dependence between the conformation of the Φ-S-S-Φ system and its optic properties. The exptl. electron and emission spectra were analyzed in terms of the calculated singlet and triplet states that allowed assigning the unique spectral pattern originating from the electrons of the C-S-S-C bridge system.
