Diethyl 3,4-bis(acetoxy­meth­yl)thieno[2,3-b]thio­phene-2,5-dicarboxyl­ate

In the title compound, C(18)H(20)O(8)S(2), the dihedral angle between the two thio­phene rings is 2.33 (7)°. The methyl C atoms of the ester groups are disordered over two positions; the site-occupancy factors of the terminal methyl C atoms are 0.632 (18):0.368 (18) and 0.623 (17):0.377 (17). The mo...

description In the title compound, C(18)H(20)O(8)S(2), the dihedral angle between the two thio­phene rings is 2.33 (7)°. The methyl C atoms of the ester groups are disordered over two positions; the site-occupancy factors of the terminal methyl C atoms are 0.632 (18):0.368 (18) and 0.623 (17):0.377 (17). The mol­ecular structure is stabilized by weak intra­molecular C—H⋯O inter­actions and the crystal structure is stabilized through weak inter­molecular C—H⋯O inter­actions.
