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.
