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

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.
