Abstract :
In the title hydrazinecarbodithioate derivative, C27H26N2O2S2, the asymmetric unit is comprised of four molecules (Z = 8 and Z′ = 4). The 4-methoxyphenyl 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-carbodithioate 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 methylenesulfanyl moiety are almost perpendicular to each other, as indicated by their torsion angles [range 93.7 (3)–114.6 (2)°]. In the crystal, molecules are linked by C—H⋯O, N—H⋯S and C—H⋯π(ring) hydrogen-bonding interactions into a three-dimensional network. Structural details of related benzyl hydrazine-1-carbodithioate are surveyed and compared with those of the title compound.
