Diethyl 2-[(1-methyl-1H-pyrrol-2-yl)methyleneamino]-5-(2-thienylmethyleneamino)thiophene-3,4-dicarboxylate
Both imine bonds of the title compound, C(21)H(21)N(3)O(4)S(2), were found to be in the E configuration. The terminal pyrrole and thiophene rings are twisted by 2.5 (3) and 2.3 (2)°, respectively, from the mean plane of the central thiophene to which they are attached. The structure is disordered...

| Sumario: | Both imine bonds of the title compound, C(21)H(21)N(3)O(4)S(2), were found to be in the E configuration. The terminal pyrrole and thiophene rings are twisted by 2.5 (3) and 2.3 (2)°, respectively, from the mean plane of the central thiophene to which they are attached. The structure is disordered by exchange of the terminal heterocyclic rings; the site occupancy factors are ca 0.8 and 0.2. The crystal packing involves some π–π stacking [3.449 (4) Å between pyrrole and terminal thiophene rings]. |
