Methyl 3-(4-methoxybenzoyl)propionate
The asymmetric unit of the title compound, C12H14O3, contains two independent molecules, in which the benzene rings are oriented at a dihedral angle of 72.08 (3)°. In the crystal structure, intermolecular C—H⋯O hydrogen bonds link the molecules into centrosymmetric dimers. There are also C—H⋯π contacts between aromatic CH groups and the benzene rings
3-(3-Bromobenzyl)-1H-isochromen-1-one
In the title compound, C16H11BrO2, the isocoumarin ring system is planar (r.m.s. deviation = 0.015 Å) and subtends a dihedral angle of 88.90 (2)° with the bromobenzene ring. In the crystal, molecules are linked, forming a three-dimensional packing pattern involving C—H⋯O interactions, Br⋯O contacts [3.4734 (10) Å] and π–π stacking interactions with centroid–centroid distances ranging from 3.667 (2) to 3.765 (2) Å
2-(2-Fluorobiphenyl-4-yl)-N′-(propan-2-ylidene)propanohydrazide
In the title compound, C18H19FN2O, the hydrazide side chain is approximately perpendicular to the central ring [dihedral angle = 76.80 (5)°]. The F atom is disordered over two positions with occupancies of 0.818 (2) and 0.182 (2). The packing consists of chains of molecules parallel to the a axis, connected by a bifurcated N—H⋯(O,N) hydrogen bond and a weak Cphenyl—H⋯O hydrogen bond. The packing is extended to a layer structure parallel to the ab plane by a weak Cphenyl—H⋯F hydrogen bond
