3-[(Furan-2-ylmethylidene)amino]-1-(4-methylphenyl)thiourea
There are two independent molecules in the asymmetric unit of the title compound, C13H13N3OS, which was obtained from a condensation reaction of N-(p-tolyl)hydrazinecarbothioamide and furfural. The dihedral angles between the mean planes of the tolyl ring and the (furan-2-ylmethylene)hydrazine unit are 39.83 (8) and 48.95 (7)° in the two molecules. The molecules both exhibit an E configuration. In the crystal, intermolecular N—H⋯N and N—H⋯S hydrogen bonds connect the two independent molecules
1-Benzylideneamino-3-(4-methylphenyl)thiourea
In the title compound, C15H15N3S, the almost planar 2-benzylidenehydrazinecarbothioamide unit (r.m.s. deviation = 0.0351 Å) is aligned at a dihedral angle of 64.42 (6)° with respect to the plane of the tolyl ring. The molecule exhibits an E configuration for the azomethine linkage. In the crystal, intermolecular N—H⋯S hydrogen bonds about centers of inversion lead to the formation of dimers
