چکیده

In the title compound, C(31)H(34)N(2)O(4), the two pyrrole rings are bent around the central methyl-ene C atom, making a dihedral angle of 64.83 (7)°. In the crystal, mol-ecules are linked into dimers via N-H⋯O=C hydrogen bonds. These dimers are packed through π⋯π inter-actions between neighboring pyrrole rings with a separation between the mean planes of symmetry-related pyrrole rings of 3.61 (2) Å and a centroid-centroid distance of 4.33 Å. Parallel phenyl groups in neighboring dimers also exhibit efficient π⋯π inter-actions, characterized by an inter-plane separation of 3.378 (8) Å and a centroid-centroid distance of 3.97 Å.

The title mol-ecule, C(30)H(28)N(2)O(4), has crystallographic twofold rotation symmetry, with the pyrrole planes forming a dihedral angle of 40.49 (4)°. The pyrrole N-H donor and adjacent ester carbonyl acceptor form R(2) (2)(10) hydrogen-bonded rings about inversion centers, leading to chains of hydrogen-bonded mol-ecules along [001].
