Diethyl 3,4-bis(acetoxy-meth-yl)thieno[2,3-b]thio-phene-2,5-dicarboxyl-ate.

ABSTRACT: In the title compound, C(18)H(20)O(8)S(2), the dihedral angle between the two thio-phene 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 mol-ecular structure is stabilized by weak intra-molecular C-H?O inter-actions and the crystal structure is stabilized through weak inter-molecular C-H?O inter-actions.

In the title compound, C(18)H(20)O(8)S(2), the dihedral angle between the two thio-phene 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 mol-ecular structure is stabilized by weak intra-molecular C-H⋯O inter-actions and the crystal structure is stabilized through weak inter-molecular C-H⋯O inter-actions. ...[more]
