Diethyl 3,4-bis-(2,5-dimethoxy-benz-yl)thieno[2,3-b]thio-phene-2,5-di-car-boxylate.

ABSTRACT: In the title compound, C(30)H(32)O(8)S(2), the dihedral angle between the two benzene rings is 18.8?(1)°. The mol-ecular structure is stabilized by weak intra-molecular C-H?O hydrogen bonds. In the crystal structure, the mol-ecules are linked via weak inter-molecular C-H?O hydrogen bonds and ?-? inter-actions between two benzene rings [centroid-centroid distance = 3.672?(1)?Å].

In the title compound, C(30)H(32)O(8)S(2), the dihedral angle between the two benzene rings is 18.8 (1)°. The mol-ecular structure is stabilized by weak intra-molecular C-H⋯O hydrogen bonds. In the crystal structure, the mol-ecules are linked via weak inter-molecular C-H⋯O hydrogen bonds and π-π inter-actions between two benzene rings [centroid-centroid distance = 3.672 (1) Å]. ...[more]
