| Abstract: | The title compound (I, W=X=Y=H, Z
= CH2Ph) is a divalent organosulphur compound of the type Ar-S-Z belonging to
the class of ortho mercaptoazo compounds. The azo group is moved away from the
sulphenyl sulphur atom to attain the stable trans azo configuration. The
sulphur atom has used hybrid orbitals (sp3) and not pure p-orbitals for
the bond formation. The benzyl units attached to the sulphenyl sulphur and the
2-benylazo unit are moved away from each other for steric reason. The molecule
is as a whole non-planar but N1 and N2 atoms are coplanar with the respective
phenyl rings to which they are attached. The S1 atom is coplanar with the
phenyl group to which it is attached. The dihedral angle between the mean
planes passing through the atoms of the thiophenyl group and the benzyl group
is 75(1)°. There is no intermolecular hydrogen bond and the molecule is
stabilised by the network of Van der Waal's interaction in their crystalline
assembly. |
