(E)-1-([1,1′-Biphenyl]-4-yl)-2-(1,3,3-trimethylindolin-2-yl-idene) ethanone

Abstract

The title compound, C25H23NO, 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 molecular conformation is s-cis with an E configuration, supported by weak intramolecular 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 interactions link the molecules..
