Abstract:
In the title compound, C(26)H(20)N(6)O(4), the two aroylhydrazone side groups exist as diastereomeres, both in the keto form in the crystal structure. The aroylhydrazone units support the mol-ecular conformation through an intra-molecular N-H⋯O hydrogen bond. Two mol-ecules are connected into a centrosymmetric dimer by inter-molecular N-H⋯N hydrogen bonds. These dimers are connected into chains along the a axis by inter-molecular O-H⋯O hydrogen bonds. The combination of these hydrogen bonds results in layers in the bc plane. The layers are further linked by weak C-H⋯π contacts to form a three-dimensional network structure.

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...
