N'-[Bis(benzyl-sulfan-yl)methyl-idene]-4-meth-oxy-benzohydrazide
Abstract:
In the title compound, C(23)H(22)N(2)O(2)S(2), the dihedral angles between the 4-meth-oxy-substituted phenyl ring and the other two phenyl rings are 84.4 (4) and 77.7 (1)°, respectively, while the dihedral angle between the two phenyl rings is 57.5 (2)°. The amino group is not involved in an N-H hydrogen bond. The crystal packing is established by inter-molecular C-H⋯O packing inter-actions involving a relatively rare weak three-center hydrogen bond between the keto O atom and H atoms of the two nearby phenyl rings, which link the mol-ecules into chains running along the a axis. Additional weak inter-molecular hydrogen-bond inter-actions between the 4-meth-oxy O atom and one of the phenyl rings and provide added stability to the crystal packing.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
