Sumario:The title compound, C(21)H(21)O(2)PS(2), was obtained from the corresponding dilithio methandiide by treatment with iodo­methane. The bond lengths and angles deviate considerably from those in the dimetallated compound. These differences are most pronounced in the PCS backbone. While the title compound features C—P and C—S distances of 1.9082 (17) and 1.8348 (17) Å, respectively, the dianion showed C—P(av) distances shortened by 11% [1.710 (4) Å] and C—S distances shortened by 12% [1.614 (3) Å]. Additionally, the P—C—S angle experiences a contraction by methyl­ation of the dianion from 121.4 (2) to 111.96 (9)° in the title compound.
