1-[4-(Di-methyl-amino)-benzyl-idene]-4-o-tolyl-thio-semicarbazide.

ABSTRACT: The asymmetric unit of the title compound, C17H20N4S, contains two independent mol-ecules, the main difference between them being the dihedral angles between the benzene rings [19.99?(17) and 9.72?(17)°]. The mol-ecules both have a trans conformation about the C=N double bond and intra-molecular C-H?S and N-H?N hydrogen bonds are observed in both mol-ecules. In the crystal, mol-ecules are linked by weak N-H?S hydrogen bonds with graph-set motif R 2 (2)(8). In each mol-ecule, all but one of the N atoms and both the S atoms are involved in hydrogen bonding.
