(E)-N′-[1-(2-Hy­droxy­phen­yl)ethyl­idene]-2-phen­oxy­acetohydrazide–2,2′-(1,1′-azinodiethyl­idyne)diphenol (2/1)

The formula unit of the title mol­ecular complex, 2C(16)H(16)N(2)O(3)·C(16)H(16)N(2)O(2), 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.
