2-[5-(2-Fluoro­phen­yl)-3-isobutyl-1H-pyrazol-1-yl]benzoic acid

In the title compound, C₂₀H₁₉FN₂O₂, the dihedral angle between the aromatic rings is 62.1 (1)°, and those between the pyrazole ring and the fluoro­benzene and benzoic acid rings are 52.1 (1) and 53.1 (1)°, respectively. In the crystal, mol­ecules are linked into [010] C(7) chains by O—H...N hydrogen bonds.

4′-Cyano­biphenyl-4-yl 7-diethyl­amino-2-oxo-2H-chromene-3-carboxyl­ate

In the title compound, C₂₇H₂₂N₂O₄, the dihedral angles between the central benzene ring and the cyano­benzene ring and the 2H-coumarin ring system (r.m.s. deviation = 0.014 Å) are 22.95 (11) and 75.59 (8)°, respectively. Both terminal C atoms of the pendant diethyl­amino group lie to the same side of the coumarin ring system [deviations = 1.366 (2) and 1.266 (2) Å]. In the crystal, mol­ecules are linked by C—H...O and C—H...N hydrogen bonds and a C—H...π inter­action, generating a three-dimensional network.
