Abstract
In the title molecule, the central pyrrole ring makes dihedral angles of 9.2 (3) and 67.6 (2)°, respectively, with the ethoxy carbonyl moiety and the fluorophenyl ring. Supramolecular aggregation is due to off-centric π–π stacking interactions involving screw-related pairs of molecules, which are further connected by N—H⋯O and C—H⋯O interactions, forming a sinusoidal pattern
In the title molecule, C12H13FN2O3, the central pyrrole ring makes a dihedral angle of 9.2 (3)° with the ethoxy carbonyl moiety whereas the fluorophenyl ring is rotated by 67.6 (2)° from the pyrrole ring. Supramolecular aggregation is due to off-centric π–π stacking interactions involving screw-related pairs of molecules, which are further connected by N—H⋯O and C—H⋯O interactions, forming a sinusoidal pattern along the [001] direction on the bc plane. Three-dimensional Hirshfeld surface analysis and two-dimensional fingerprint plots confirm the contributions of these interactions.
