SYNTHESES AND STRUCTURES OF S4N4(OCH3)(2) AND CH3OS4N4(O)CL

The reaction of S4N4Cl2 with CH3OH gives S4N4(OCH3)(2), a simple dimet hoxoderivative of S4N4. Its overall geometry is analogous to other com pounds of the S(4)N(4)X(2) type. The chlorination of S4N4(OCH3)(2) lea ds to the oxidation of one sulfur atom to S-VI and CH3OS4N4(O)Cl is fo rmed. The compounds were characterized by ir spectroscopy and their cr ystal structures were determined from single crystal diffraction data collected at -153 degrees C. The presence of S-VI in the molecule of C H3OS4N4(O)Cl is manifested by a marked shortening of the bonds formed by this atom as compared with S4N4Cl2 and S4N4(OCH3)(2).
