1-[4-(Di­methyl­amino)­benzyl­idene]-4-o-tolyl­thio­semicarbazide

The asymmetric unit of the title compound, C(17)H(20)N(4)S, contains two independent mol­ecules, the main difference between them being the dihedral angles between the benzene rings [19.99 (17) and 9.72 (17)°]. The mol­ecules both have a trans conformation about the C=N double bond and intra­molecular C—H⋯S and N—H⋯N hydrogen bonds are observed in both mol­ecules. In the crystal, mol­ecules are linked by weak N—H⋯S hydrogen bonds with graph-set motif R (2) (2)(8). In each mol­ecule, all but one of the N atoms and both the S atoms are involved in hydrogen bonding.
