title: Ethyl 2-benzyl-3-[3-(4-chloro-phen-yl)-1-phenyl-1H-pyrazol-4-yl]-4,6-dioxo-5-phenyl-octa-hydro-pyrrolo-[3,4-c]pyrrole-1-carboxyl-ate.
abstract: The title compound, C(37)H(31)ClN(4)O(4), crystallizes with two mol-ecules (A and B) in the asymmetric unit. The pyrrole rings in both mol-ecules are connected via cis fusion, whereas one ring has a twisted conformation and the other assumes a half-chair conformation. In the crystal, the A mol-ecules form inversion dimers via a pair of C-H⋯Cl inter-actions, while the B mol-ecules form chains propagating in [1[Formula: see text]0], via C-H⋯O inter-actions. In the crystal, there are also a number of C-H⋯π inter-actions present.
