(E)-3-(2-Chloro-phen-yl)-1-(4-chloro-phen-yl)prop-2-en-1-one.

ABSTRACT: The title compound, C(15)H(10)Cl(2)O, adopts an E configuration with respect to the C=C bond of the propenone unit. The dihedral angle between the two benzene rings is 32.4?(1)°. Intra-molecular C-H?O and C-H?Cl hydrogen bonds generate an S(5)S(5)S(5) motif. In addition, the crystal structure is stabilized by weak inter-molecular C-H?O hydrogen bonds.

Project description:The title compound, C(15)H(10)Cl(2)O, is a chalcone with 3-chloro-phenyl and 4-chloro-phenyl substituents bonded at the opposite ends of a propenone group, the biologically active region. The dihedral angle between mean planes of these two chloro-substituted benzene rings is 46.7?(7)° compared to 46.0?(1) and 32.4?(1)° in similar published sructures. The angles between the mean plane of the prop-2-en-1-one group and the mean planes of the 3-chloro-phenyl and 4-chloro-phenyl rings are 24.1?(2) and 29.63°, respectively. While no classical hydrogen bonds are present, weak inter-molecular C-H??-ring inter-actions are observed, which contribute to the stability of crystal packing.

(E)-3-(2-Chloro-phen-yl)-1-(4-nitro-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(15)H(10)ClNO(3), a substituted chalcone, the 2-chloro-phenyl and 4-nitro-phenyl rings make a dihedral angle of 26.48 (6)°. The nitro group makes a dihedral angle of 11.64 (7)° with the plane of the benzene ring to which it is bound. Weak intra-molecular C-H⋯O and C-H⋯Cl inter-actions involving the enone groups generate S(5) ring motifs, which help to stabilize the planarity of the 3-(2-chloro-phen-yl)prop-2-en-1-one segment of the mol-ecule. In the crystal structure, adjacent mol-ecules are stacked in a head-to-tail fashion into columns along the a axis by π-π inter-actions [centroid-centroid distance = 3.6955 (8) Å]. Neighbouring columns are linked by weak C-H⋯O inter-actions.

(E)-1-(4-Amino-phen-yl)-3-(2-chloro-phen-yl)prop-2-en-1-one.

Project description:The title compound, C(15)H(12)ClNO, a substituted chalcone, adopts an E configuration with respect to the C=C bond of the enone unit. The mol-ecule is not planar, as can be seen from the dihedral angle of 28.9 (2)° between the two rings which are twisted from each other. The enone segment of the mol-ecule is not coplanar with the chloro-phenyl ring, making a dihedral angle of 23.4 (3)° with it. The amino group is also not coplanar with the ring to which it is bound, making a dihedral angle of 35 (4)°. In the crystal structure, adjacent mol-ecules are linked by N-H⋯O inter-actions into one-dimensional infinite chains along the c axis, and are further stacked as one-dimensional zigzag chains down the b axis, forming two-dimensional extended networks parallel to the bc plane.
