Crystal structure of benzyl N'-[(1E,4E)-1,5-bis-(4-meth-oxy-phen-yl)penta-1,4-dien-3-yl-idene]hydrazine-1-carbodi-thio-ate.

ABSTRACT: In the title hydrazinecarbodi-thio-ate derivative, C27H26N2O2S2, the asymmetric unit is comprised of four mol-ecules (Z = 8 and Z' = 4). The 4-meth-oxy-phenyl rings are slightly twisted away from their attached olefinic double bonds [torsion angles = 5.9?(4)-19.6?(4)°]. The azomethine double bond has an s-trans configuration relative to one of the C=C bonds and an s-cis configuration relative to the other [C=C-C= N = 147.4?(6)-175.7?(2) and 15.3?(3)-37.4?(7)°, respectively]. The torsion angles between the azomethine C=N double bond and hydrazine-1-carbodi-thio-ate moiety indicate only small deviations from planarity, with torsion angles ranging from 0.9?(3) to 6.9?(3)° and from 174.9?(3) to 179.7?(2)°, respectively. The benzyl ring and the methyl-enesulfanyl moiety are almost perpendicular to each other, as indicated by their torsion angles [range 93.7?(3)-114.6?(2)°]. In the crystal, mol-ecules are linked by C-H?O, N-H?S and C-H??(ring) hydrogen-bonding inter-actions into a three-dimensional network. Structural details of related benzyl hydrazine-1-carbodi-thio-ate are surveyed and compared with those of the title compound.

(1E,4E)-1,5-Bis(thio-phen-3-yl)penta-1,4-dien-3-one.

Project description:The title compound, C(13)H(10)OS(2), exhibits twists between the central C(3)O and ethene residues [O-C-C-C torsion angles = -8.4?(3) and 11.8?(3)°], and between the ethene and adjacent thio-phenyl residues [C-C-C-C torsion angles = -4.2?(3) and 10.5?(3)°]. As a result, the mol-ecule is non-planar, the dihedral angle formed between the terminal thio-phenyl groups being 15.45?(10)°. The presence of C-H?O inter-actions involving the bifurcated carbonyl O atom leads to supra-molecular arrays in the ac plane. These are linked into a three-dimensional architecture by C-H?? inter-actions involving both thio-phenyl residues.

Project description:The title compound, C(19)H(18)O, crystallizes in a non-centrosymmetric space group although the mol-ecule has no chiral centre.

In the crystal, mol-ecules are linked by inter-molecular C-H?O and C-H?? weak inter-actions into a three-dimensional network.

Project description:In the title compound, C(19)H(12)F(6)O, a monoketone derivative of curcumin, both double bonds have a trans conformation.

(1E,4E)-1,5-Bis(2,4,6-trimeth-oxy-phen-yl)penta-1,4-dien-3-one.

Project description:There are two crystallographically independent mol-ecules in the asymmetric unit of the title bis-chalcone derivative, C(23)H(26)O(7). The mol-ecules are unsymmetrical and almost planar: the dihedral angle between two benzene rings is 1.04?(7)° in one mol-ecule and 2.31?(7)° in the other. The central penta-1,4-dien-3-one fragment makes dihedral angles of 7.61?(7) and 6.82?(7)° with the two adjacent benzene rings in one mol-ecule, while the corresponding values are 7.85?(7) and 9.42?(6)° in the other. In both mol-ecules, the three meth-oxy groups of the two 2,4,6-trimeth-oxy-phenyl units are coplanar with the attached benzene rings [C-O-C-C- torsion angles of -1.5?(2), -7.2?(2) and 4.1?(2)° in one mol-ecule and -0.7?(2), -5.5?(2) and -0.6?(2)° in the other]. The mol-ecular conformations are stabilized by weak intra-molecular C-H?O inter-actions generating two S(6) ring motifs. In the crystal, mol-ecules are linked by weak inter-molecular C-H?O inter-actions into zigzag chains parallel to the c axis. The crystal structure is further stabilized by C-H?? inter-actions and ?-? inter-actions with centroid-centroid distances of 3.6433?(8)?Å.
