N,N'-Bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine

In the title compound, C₁₉H₂₂N₂O₂, the average N...O separation of 2.580 (4) Å is indicative of intramolecular hydrogen bonding within each salicylideneimine unit. The two aromatic rings are inclined at an angle of 68.66 (11)° and this results in a conformation which is inappropriate for quadridentate ligand activity.
