Crystal structure of N-(2-benzoyl-5-ethynylphenyl)quinoline-2-carboxamide

Abstract

In the title compound, C25H16N2O2, the quinoline ring system is essentially planar, with a maximum deviation of 0.030 (1) Å, and forms a dihedral angle of 20.9 (1)° with benzoyl benzene ring. The unsubstituted phenyl ring forms dihedral angles of 52.7 (1)° with the quinoline ring system and 54.1 (1)° with the ethynyl-substituted benzene ring. The molecule contains an intramolecular bifurcated N—H...(O,N) hydrogen bond, forming S(5) and S(6) rings, which may influence the conformation of the molecule. In the crystal, weak C—H...O hydrogen bonds link the molecules into a three-dimensional network. In addition, the three-dimensional structure contains π–π stacking interactions, with centroid–centroid distances of 3.695 (1) and 3.751 (1) Å.
