The formula unit of the title molecular complex, 2C16H16N2O3·C16H16N2O2, consists of two (E)-N′-[1-(2-hydroxyphenyl)ethylidene]-2-phenoxyacetohydrazide molecules and one molecule of 2,2′-(1,1′-azinodiethylidyne)diphenol, with the latter located on a crystallographic inversion center. The acetohydrazide molecules are linked into a supermolecular chain along the c axis by intermolecular N—H⋯O hydrogen bonds. There are also intramolecular O—H⋯N hydrogen bonds in both the acetohydrazide and diphenol molecules.
