1,2-Bis(N'-benzoyl-thio-ureido)benzene
Abstract:
The title compound, C(22)H(18)N(4)O(2)S(2), was characterized by (1)H and (13)C NMR, solid-state IR spectroscopy and X-ray crystallographic techniques. The crystal structure determination reveals that the twisting modes of the two side arms are different [C-N-C-O and C-N-C-N torsion angles = -1.2 (3) and 1.1 (3)°, respectively, in one arm and 24.1 (3) and -5.1 (3)°, respectively, in the other]. The crystal structure involves N-H⋯O and N-H⋯S hydrogen bonds.

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...
