(E)-4-(Benz-yloxy)benzaldehyde thio-semicarbazone
Abstract:
In the title compound, C(15)H(15)N(3)OS, the thio-semicarbazone group adopts an E configuration with respect to the C=N bond. The benzaldehyde thio-semicarbazone fragment is almost planar [maximum deviation = 0.012 (1) Å], while the dihedral angle between the benz-yloxy and phenyl rings is 72.48 (5)°. In the crystal structure, mol-ecules are inter-connected by N-H⋯N and N-H⋯S hydrogen bonds, forming a two-dimensional network parallel to the bc plane and are further stacked along the a axis by π-π inter-actions [centroid-centroid separation 3.9043 (7) Å]. The crystal structure is also stabilized by C-H⋯π inter-actions.
