| Abstract: | The reaction of S4N4Cl2 with CH3OH gives S4N4(OCH3)2, a simple dimethoxoderivative of S4N4. Its overall geometry is analogous to other compounds of the S4N4X2 type. The chlorination of S4N4(OCH3)2 leads to the oxidation of one sulfur atom to SVI and CH3OS4N4(O)Cl is formed. The compounds were characterized by ir spectroscopy and their crystal structures were determined from single crystal diffraction data collected at ?153°C. The presence of SVI in the molecule of CH3OS4N4(O)Cl is manifested by a marked shortening of the bonds formed by this atom as compared with S4N4Cl2 and S4N4(OCH3)2. |
