Methyl 4-benz­yloxy-2-hy­droxy­benzoate

In the title compound, C₁₅H₁₄O₄, the dihedral angle between the benzene rings is 67.18 (8)°. The C_a—C_m—O—C_a (a = aromatic and m = methyl­ene) torsion angle is 172.6 (3)° and an intra­molecular O—H...O hydrogen bond generates an S(6) ring. In the crystal, mol­ecules are linked by C—H...O hydrogen bonds into zigzag chains propagating in [001] and C—H...π inter­actions also occur.

(2E)-3-(2-Bromo­phen­yl)-1-(5-bromo­thio­phen-2-yl)prop-2-en-1-one

The asymmetric unit of the title compound, C₁₃H₈Br₂OS, contains two mol­ecules, in which the dihedral angles between the thio­phene and benzene rings are 10.5 (3) and 33.2 (4)°. There are no significant directional inter­actions in the crystal.

4-Nitro­phenyl 4-hy­droxy-3-methyl­benzoate

The asymmetric unit of the title compound, C₁₄H₁₁NO₅, contains two independent mol­ecules in which the dihedral angles between the benzene rings are 89.27 (16) and 77.14 (12)°. In the crystal, mol­ecules are linked by O—H...O hydrogen bonds, generating C(8) chains propagating in [010] for one mol­ecule and [001] C(8) chains for the other. The chains are connected by C—H...O hydrogen bonds and π–π inter­actions [shortest centroid–centroid distance = 3.5908 (12)°], generating a three-dimensional network.
