Crystal structure and Hirshfeld surface analysis of 4-bromo-6-(4-chlorophenyl)-6,7-dihydro-5 <i>H</i> -furo[2,3- <i>f</i> ]isoindol-5-one

The mol-ecule of the title compound, C₁₆H₉BrClNO₂, contains furan and phenyl rings and an iso-indole ring system. The phenyl ring subtends a dihedral angle of 10.3 (2)° with the fused ring system. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional network nearly parallel to the <i>ab</i> plane, enclosing <i>R</i> ² ₂(6), <i>R</i> ⁴ ₄(12), <i>R</i> ⁴ ₄(14), <i>R</i> ⁴ ₄(18) and <i>R</i> ⁴ ₄(20) ring motifs. π-π stacking between the centroids of parallel rings [centroid-centroid distances = 3.919 (3)-3.695 (3) Å] helps to consolidate the packing. Hirshfeld surface analysis revealed that the most important contributions for the crystal packing are from H⋯H (21.2%), H⋯Cl/Cl⋯H (14.7%), H⋯O/O⋯H (13.9%), H⋯C/C⋯H (13.1%), H⋯Br/Br⋯H (12.3%) and C⋯C (11.6%) inter-actions.
