title: Methyl 2,3-(3,6,9-trioxaundecane-1,11-diyldithio)-1,4,5,8-tetra-thia-fulvalene-6-carboxyl-ate.
abstract: In the title mol-ecule, C(16)H(20)O(5)S(6), the two five-membered rings form a dihedral angle of 4.7 (3)°. The crystal packing exhibits weak inter-molecular C-H⋯O hydrogen bonds, which link the mol-ecules into chains propagating in [10], and π-π inter-actions, indicated by the short distances [3.756 (5) Å] between the centroids of five-membered rings from mol-ecules related by translation along the b axis.
