4-Methyl­phenyl quinoline-2-carboxyl­ate

In the title compound, C₁₇H₁₃NO₂, two mol­ecules crystallize in the asymmetric unit. The dihedral angle between the mean planes of the quinoline and benzene rings are 78.3 (4) and 88.2 (3)°. The carboxyl­ate group is twisted slightly from the quinoline ring by 7.1 (2) and 13.3 (4)°, respectively. In the crystal, weak C—H...O inter­actions are observed. Further stabilization is provided by weak π–π stacking inter­actions, with centroid–centroid distances of 3.564 (9)/3.689 (2) and 3.830 (1)/3.896 (5)Å, respectively.

2-(4-Methyl­phen­yl)acetohydrazide

In the title compound, C₉H₁₂N₂O, the dihedral angle between the benzene ring and the mean plane of the acetohydrazide group is 88.2 (7)°. In the crystal, N—H...O hydrogen bonds and weak C—H...O inter­actions link the mol­ecules into infinite ribbons along [001].
