Abstract

In the title compound, C20H18Cl2N2O3, the dihedral angles between the central 2,5-dihydro-1H-pyrrole ring and the two phenyl rings are 74.87 (9) and 29.09 (9)degrees. There is a short N-H center dot center dot center dot O contact in the molecule with an S(5) ring motif. In the crystal, pairs of N-H center dot center dot center dot O hydrogen bonds link adjacent molecules into inversion dimers which are reinforced by C-H center dot center dot center dot O hydrogen bonds, forming an R-1(2) (6) R-2(2)(10) R-1(2)(6) ring motif. The dimers are linked by further C-H center dot center dot center dot O hydrogen bonds forming slab-like two-dimensional networks lying parallel to (001).
