The title compound, C38H40Br2N2, crystallizes in the triclinic space group P-1 with two molecules in a unit cell. The two carbazole groups are nearly coplanar, making a dihedral angle of 16.90 (5)°, and are bridged by vinyl. The crystal structure features π-π and C—H⋯π interactions and C—H⋯Br short contacts.

We describe the crystal structures of four indole derivatives with a phenyl ring at the 2-position and different carbonyl-linked substituents at the 3-position, namely 1-(2-phenyl-1H-indol-3-yl)ethanone, C16H13NO, (I), 2-cyclohexyl-1-(2-phenyl-1H-indol-3-yl)ethanone, C22H23NO, (II), 3,3-dimethyl-1-(2-phenyl-1H-indol-3-yl)butan-1-one, C20H21NO, (III), and 3-benzoyl-2-phenyl-1H-indole, C21H15NO, (IV). In each case, the carbonyl-group O atom lies close to the indole-ring plane and points towards the benzene ring. The dihedral angles between the indole ring system and 2-phenyl ring for these structures are clustered in a narrow range around 65°. The dominant intermolecular interaction in each case is an N—H⋯O hydrogen bond, which generates a C(6) chain, although each structure possesses a different crystal symmetry. The C(6) chains are consolidated by different (C—H⋯O, C—H⋯π and π-π stacking) weak interactions, with little consistency between the structures.

The title compound, C19H18N4O2, crystallizes with two independent molecules in the asymmetric unit. The triazole ring is inclined to the benzene rings by 9.63 (13) and 87.37 (12)° in one molecule, and by 4.46 (13) and 86.15 (11)° in the other. In the crystal, classical N—H⋯N hydrogen bonds, weak C—H⋯O hydrogen bonds and weak C—H⋯π interactions link the molecules into a three-dimensional supramolecular network. Hirshfeld surface analysis and two-dimensional fingerprint plots were used to investigate the intermolecular interactions present in the crystal, indicating that the most important contributions for the crystal packing are from H⋯H (51.4%), H⋯C/C⋯H (26.7%), H⋯O/O⋯H (8.9%) and H⋯N/N⋯H (8%) interactions.
