- The title compound, \(C_{21}H_{21}O_2PS_2\), was obtained from the corresponding dilithio methandiide by treatment with iodo-methane. 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 aThe title compound, \(C_{21}H_{21}O_2PS_2\), was obtained from the corresponding dilithio methandiide by treatment with iodo-methane.

Additionally, the P-C-S angle experiences a contraction by methyl-ation of the dianion from 121.4(2) to 111.96(9)° in the title compound.…
