(2E)-3-(3-Nitro-phen-yl)-1-[4-(piperidin-1-yl)phen-yl]prop-2-en-1-one.

ABSTRACT: In the title compound, C(20)H(20)N(2)O(3), the piperidine ring adopts a chair conformation and its mean plane forms dihedral angles of 19.63 (9) and 19.44 (9)°, respectively, with the benzene and the nitro-substituted benzene ring. The benzene and nitro-substituted benzene rings are almost coplanar and make a dihedral angle of 4.78 (8)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds into two-dimensional networks parallel to the ab plane. The crystal packing is further stabilized by π-π inter-actions [maximum centroid-centroid distance = 3.7807 (12) Å].

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

Project description:The title compound, C(16)H(13)NO(3), crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the 4-methyl-phenyl and 3-nitro-phenyl groups is 4.0 (3)° in mol-ecule A and 16.2 (7)° in mol-ecule B. Inter-molecular C-H⋯O hydrogen bonding involving the O atoms of the 3-nitro-phenyl group of both independent mol-ecules link the mol-ecules into layers approximately parallel to the (110) plane. The layers are held together by π-π stacking inter-actions between the 4-methyl-phenyl ring of mol-ecule A and the 3-nitro-phenyl ring of mol-ecule B of the adjacent layer, with the distance between the centroids of inter-acting rings being 3.6987 (7) Å.

Project description:In the title compound, C(17)H(14)BrNO(5), the dihedral angle between the 3-bromo-substituted benzene ring and the 4,5-dimeth-oxy-2-nitro-phenyl ring is 15.2 (1)°. The dihedral angles between the mean plane of the propenone group and the mean planes of the 3-bromo-substituted benzene and 4,5-dimeth-oxy-2-nitro-phenyl rings are 6.9 (6) and 20.5 (5)°, respectively. Weak inter-molecular C-H⋯O inter-actions contribute to crystal stability and π-π inter-actions [centroid-centroid distances = 3.7072 (18) and 3.6326 (18) Å] are also observed.

(2E)-1-[5-Methyl-1-(4-methyl-phen-yl)-1H-1,2,3-triazol-4-yl]-3-[4-(piperidin-1-yl)phen-yl]prop-2-en-1-one.

Project description:Two independent mol-ecules comprise the asymmetric unit of the title compound, C24H26N4O. The major difference between them is found in the relative orientation of the triazole-bound p-tolyl group which have the opposite sense of twist [N-N-C-C torsion angles = 55.8?(3) and -49.8?(3)°]. The chalcone residue is almost coplanar with the triazole ring [N-C-C-O and C-C-C-C torsion angles = -178.9?(2) and -178.5?(2)°, respectively; cf. 177.9?(3) and 168.5?(3)°, respectively, in the second mol-ecule]. The conformation about each C=C double bond is E and in each case the triazole methyl group is syn to the carbonyl O atom. In the crystal, mol-ecules aggregate into layers parallel to (-113). The first independent mol-ecule self-associates into a layer via C-H?O and C-H?? inter-actions. By contrast, layers comprising the second independent mol-ecule do not feature specific inter-actions between mol-ecules. The global crystal packing comprises alternating layers.

(2E)-1-(2,4-Dichloro-phen-yl)-3-[3-(4-nitro-phen-yl)-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one.

Project description:In the title compound, C(24)H(15)Cl(2)N(3)O(3), the C=C double bond is E configured. The 1-phenyl-1H-pyrazole moiety is roughly planar (r.m.s. deviation of all fitted non-H atoms = 0.0780 Å), but the mean planes of the two components are inclined at an angle of 9.95 (7)°. The mean plane defined by the non-H atoms of the 1H-pyrazole ring encloses angles of 9.95 (7), 24.54 (6) and 43.02 (6)° with the mean planes of the different benzene rings. In the crystal, C-H⋯O contacts are present and result in the formation of a double-layer two-dimensional network lying parallel to (110). The shortest inter-centroid distance between two aromatic systems is 3.5455 (7) Å and is apparent between two pyrazole systems. Further π-π inter-actions are manifest between a pair of 4-nitro-phenyl rings [centroid-to-centroid distance = 3.6443 (7) Å] and a pair of 2,4-dichloro-phenyl rings [centroid-to-centroid distance = 3.7797 (7) Å].

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

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 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⋯π-ring inter-actions are observed, which contribute to the stability of crystal packing.

Project description:The title compound, C(15)H(10)Br(2)O, is a chalcone with 2-bromo-phenyl and 4-bromo-phenyl rings bonded to opposite sides of a propenone group.

Project description:In the title compouund, C(15)H(10)F(2)O, the mol-ecule exists in an E conformation with respect to the C=C bond [1.3382 (16) Å].

In the crystal, mol-ecules are linked by C-H⋯F and C-H⋯O inter-actions into sheets lying parallel to the bc plane.
