2-[(E)-(5-tert-Butyl-2-hydroxy-phen-yl)-diazen-yl]benzoic acid
Abstract:
The title compound, C(17)H(18)N(2)O(3), is approximately planar, owing in part to an intra-molecular bifurcated O-H⋯(N,O) hydrogen bond; the dihedral angle between the two aromatic rings is 23.86 (9)°. In the crystal struture, centrosymmetrically related mol-ecules associate into dimers via the eight-membered carboxyl-ate {⋯H-O-C=O}(2) synthon.

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...
