4-Hydroxy-3-methoxybenzaldehyde 4-phenylthiosemicarbazone

What is it about?

In the title compound, C15H15N3O2S, the central C-N-N-C unit has an anti conformation [torsion angle = -170.17 (15)°]. The phenyl substituent is oriented perpendicular to this unit [dihedral angle of 89.2 (1)°], whereas the substituted ring is rotated out of this plane by only 18.86 (17)°. In the crystal, mol­ecules are linked by pairs of N-H...S hydrogen bonds into inversion dimers that are further connected via N-H...O and O-H...S hydrogen bonds into a three-dimensional network.
