(E,Z)-1-(4-Chlorophenyl)-5-phenyl-5-(phenylsulfanyl)penta-2,4-dien-1-one
The penta-2,4-dien-1-one fragment of the title compound, C23H17ClOS, is twisted by 20.0 (3)°, as measured by the dihedral angle between the planes of the carbonyl group and its attached C atom and the distant C=C double bond and its attached C atom. The 4-chloro-phenyl group forms a dihedral angle of 4.0 (3)° with the adjacent carbonyl group. Conjugation between the phenyl ring and the C=C doub...

In the title mol-ecule, C17H12F2O3, the dihedral angle between the benzene rings is 8.6 (2)°. In the crystal, two pairs of O-H⋯O hydrogen bonds connect the mol-ecules into inversion dimers. In addition, weak C-H⋯F hydrogen bonds link the dimers into a two-dimensional network parallel to (10-4). The carbonyl O atom is an acceptor for two weak intra-molecular hydrogen bonds.

The molecule of the title compound, C(13)H(10)N(2)O(4), is nearly planar with a dihedral angle between the two aromatic rings of 2.24 (9)°. The NH group forms an intramolecular hydrogen bond with the carbonyl O atom. The mol-ecules form dimers about inversion centers in the crystal structure via inter-molecular O-H⋯O hydrogen bonds.

In the title compound, C21H22ClNO3, the penta-diene unit is nearly planar [maximum deviation = 0.023 (1) Å], but the carbonyl O atom deviates significantly [by 0.304 (1) Å] from its mean plane, which is twisted with respect to the phenyl and chloro-benzene rings by 71.34 (13) and 46.40 (13)°, respectively. In the crystal, inversion-related molecules are linked by two pairs of O-H⋯O hydrogen bon...

In the title compound, C(27)H(20)ClNO, the quinoline ring forms a dihedral angle of 62.53 (5)° with the substituent benzene ring. In the crystal, inter-molecular C-H⋯Cl inter-actions link the mol-ecules into chains along the b axis. Inter-molecular C-H⋯N and C-H⋯O hydrogen bonds further consolidate the structure into a three-dimensional network. The unit cell contains four solvent-accessible vo...
