In the title compound, C30H32O8S2, the dihedral angle between the two benzene rings is 18.8 (1)°. The molecular structure is stabilized by weak intramolecular C—H⋯O hydrogen bonds. In the the molecules are linked via weak intermolecular C—H⋯O hydrogen bonds and π–π interactions between two benzene rings [centroid–centroid distance = 3.672 (1) Å].

To a solution of Diethyl 3,4-bis-(acetoxymethyl) thieno[2,3,-b]thiophene-2,5-dicarboxylate (0.7 g, 1.63 mmol) in dry 1,2-dichloroethane (10 ml), Ferric Chloride (0.05 g, 0.32 mmol) and 1,4-dimethoxybenzene (0.54 g, 3.92 mmol) were added under nitrogen atmosphere. The reaction mixture was refluxed for 20 hr, then it was poured over crushed ice (40 g) containing 1 ml of Conc.HCl. Ferric chloride was carefully filtered off and the filtrate was evaporated under reduced pressure giving crude product and it was crystallized from methanol affording pure product.
H atoms were positioned geometrically and refined using a riding model with C—H = 0.93Å and Uiso(H) = 1.2Ueq(C) for aromatic C—H, with C—H = 0.97Å and Uiso(H) = 1.2Ueq(C) for methylene and C—H = 0.96Å and Uiso(H) = 1.5Ueq(C) for methyl.
In continuation of our studies on thiophene derivatives which exhibit biological activities such as anti-protozoal (Tapia et al., 2003), antitumor (Dallemagne et al., 2003), we report the
of the title compound. The geometric parameters of the title compound (Fig. 1) agree with the reported similar structures (Dufresne & Skene, 2008; Gunasekaran et al., 2009). The dihedral angle between the phenyl rings C14—C19 and C23—C28 is 18.8 (1)°.The molecular structure is stabilized by intramolecular C—H···O hydrogen bonds. In the π···π [Cg4···Cg4 (1 - x, -y, -z) = 3.672 (1) Å; Cg4 is the centroid of C23—C28 ring] interactions. The intermolecular C17—H17···O2 hydrogen bond generates a twenty-membered ring, with a graph-set motif of R22(20) (Bernstein et al., 1995).
the molecules are linked via intermolecular C—H···O hydrogen bonds (see, Fig. 2), and are further consolidated byFor the biological activity of thiophene derivatives, see: Tapia et al.

In continuation of our studies on thiophene derivatives which exhibit biological activities such as anti-protozoal (Tapia et al., 2003), antitumor (Dallemagne et al., 2003), we report the crystal structure of the title compound. The geometric parameters of the title compound (Fig. 1) agree with the reported similar structures (Dufresne & Skene, 2008; Gunasekaran et al., 2009). The dihedral angle between the phenyl rings C14—C19 and C23—C28 is 18.8 (1)°.
The molecular structure is stabilized by intramolecular C—H···O hydrogen bonds. In the crystal structure, the molecules are linked via intermolecular C—H···O hydrogen bonds (see, Fig. 2), and are further consolidated by π···π [Cg4···Cg4 (1 - x, -y, -z) = 3.672 (1) Å; Cg4 is the centroid of C23—C28 ring] interactions. The intermolecular C17—H17···O2 hydrogen bond generates a twenty-membered ring, with a graph-set motif of R22(20) (Bernstein et al., 1995).
