title: Methyl 2,2-dimeth-oxy-5,5-bis-(methyl-sulfan-yl)-3-oxopent-4-enedithio-ate.
abstract: In the title mol-ecule, C(10)H(16)O(3)S(4), a short intra-molecular S⋯O(=C) distance [2.726 (2) Å] indicates the presence of a nonbonding attractive inter-action. In the crystal, mol-ecules are linked into centrosymmetric dimers via weak inter-molecular C-H⋯O and S⋯S [3.405 (3) Å] inter-actions. These dimers are linked by further weak C-H⋯O inter-actions into columns along the a axis.
