title: Dibenzyl 3,3'-diethyl-4,4'-dimethyl-2,2'-methylenebis(pyrrole-5-carboxylate).
abstract: 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.
