چکیده
The title compound, C(25)H(23)NO, consists of a biphenyl-4-carbonyl unit attached to an exocyclic double bond group at position 2 of an indole unit, which presents methyl groups as substituents at positions 1 and 3. The mol-ecular conformation is s-cis with an E configuration, supported by weak intra-molecular C-H⋯O contacts involving the methyl groups and the carbonyl function. The rings of the biphenyl group are twisted by 37.13 (5)°. In the crystal, C-H⋯O and C-H⋯π inter-actions link the molecules.

The title compound, C20H21N3O, has crystallographic mirror symmetry with all non-H atoms apart from the methyl C atom of the CMe2 group lying on the mirror plane. Mol-ecules are linked into planar sheets parallel to (010) by phen-yl-azo C-H⋯N and phen-yl-ethanone C-H⋯O inter-actions. Methyl C-H⋯π inter-actions provide crosslinking between the planes.
