Crystal structure and Hirshfeld surface analysis of the chalcone derivative (2E)-3-[4-(di­phenyl­amino)phen­yl]-1-[4-(prop-1-yn-2-yl­oxy)phen­yl]prop-2-en-1-one

Abstract

The mol­ecule adopts an s-cis conformation with respect to the C=O and C—C bonds of the chalcone bridge.

In the crystal structure of the title chalcone derivative, C₃₀H₂₃NO₂, the mol­ecule adopts an s-cis conformation with respect to the C=O and C=C bonds. The tri­phenyl­amine moiety has a propeller-type shape, with dihedral angles between the mean planes of pairs of phenyl rings of 72.1 (6), 69.7 (1) and 65.6 (6)°. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming chains extending parallel to [010]. In addition, weak C—H⋯π inter­actions consolidate the crystal packing. One of the phenyl rings of the tri­phenyl­amine moiety is disordered over two sets of sites.
