(2E,4E)-1-(2-Hy-droxy-phen-yl)-5-phenyl-penta-2,4-dien-1-one.

ABSTRACT: In the structure of the title chalcone, C(17)H(14)O(2), derived from cinnamaldehyde, the olefine group has a trans configuration. The mol-ecular conformation is stabilized by an intra-molecular O-H?O hydrogen-bond inter-action with graph-set motif S(6).

Crystal structure of (2E,4E)-5-[bis-(2-hy-droxy-eth-yl)amino]-1-(4-chloro-phen-yl)-5-phenyl-penta-2,4-dien-1-one.

Project description: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 bonds, forming chains propagating along [01-1], enclosing R (2) 2(16) and R (2) 2(22) ring motifs. The chains are linked via C-H?O hydrogen bonds and C-H?? inter-actions into a three-dimensional supra-molecular architecture.

(2Z,4E)-1-(5-Fluoro-2-hy-droxy-phen-yl)-5-(4-fluoro-phen-yl)-3-hy-droxy-penta-2,4-dien-1-one.

Project description: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.

(2E,4E)-1-(6-Chloro-2-methyl-4-phenyl-3-quinol-yl)-5-phenyl-penta-2,4-dien-1-one.

Project description: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.

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 voids, each with a volume of 35?Å(3), but no significant electron density was found in them.
