Abstract:
In the crystal structure of the title compound, C26H36N2O4, the tripodal mol-ecule exists in a conformation in which the substituents attached to the central arene ring are arranged in an alternating order above and below the ring plane. The heterocyclic unit is inclined at an angle of 79.6 (1)° with respect to the plane of the benzene ring. In the crystal, the mol-ecules are connected via N-H⋯O bonds, forming infinite supra-molecular strands. Inter-strand association involves weak C-H⋯O and C-H⋯π inter-actions, with the pyridine ring acting as an acceptor in the latter case.

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...
