✦ Synopsis

The crystal and molecular structures of the title compounds were determined by X-ray diffraction technique from diffractometer intensity measurements. It has been found that two homologous disulfides, bis(dimethoxythiophosphory0 disulfide 1 and bis(dineopentoxythiophosphory0 disulfide 2, form different molecular and crystal structures with space groups C2Ic and P?, respectively. These results were confirmed by 3'P CP MAS NMR studies, which showed that under favorable conditions the solid state N M R may lead to determination of the number of crystallographically unique phosphovus atoms. Moreover, the variation of the disulfide S-S bond length versus torsional P-s-S-P angles was observed.
