چکیده
The structure of the title compound, C(16)H(19)N(3)O(4)S, shows the planes described by the thio-phene and the pyrroles are twisted by 17.06 (4)°. Additionally, the structure shows the azomethine bond adopts the E configuration, while the pyrrole is disordered as a heterocycle flip [occupancy ratio 0.729 (5):0.271 (5)]. The three-dimensional network is well packed and involves N-H⋯O hydrogen bonding and π-π stacking [centroid-centroid distance = 4.294 (8) Å].

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 thio-phene rings are twisted by 2.5 (3) and 2.3 (2)°, respectively, from the mean plane of the central thio-phene 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. Th...
