Abstract
In the reaction of naphthalene-2,3-diol and 4-aminoantipyrine in the presence of acetic acid, the amine function is acetylated and the resulting acetamide co-crystallizes with the diol in the title compound, C13H15N3O2·C10H8O2, with 1:1 molar stoichiometry. The two components are linked by two O–H⋯O=C hydrogen bonds. One of the hydroxy groups interacts with the pyrazolone carbonyl O atom and the other hydroxy group interacts with the amide O atom of another component, generating a chain motif. Adjacent chains are linked into a layer motif via N—H⋯O interactions involving only the heterocyclic acetamide component.
