title: 1,3-Bis[2-(2-hydroxybenzylideneamino)phenoxy]propane.
abstract: The title compound [systematic name: 2,2'-[1,3-propanediyldioxydi-o-phenylenebis(nitrilomethylidyne)]diphenol], C(29)H(26)N(2)O(4), exists as the phenol-imine form in the crystal, and there are strong intramolecular O-H...N hydrogen bonds, with O...N distances of 2.545 (2) and 2.579 (2) A. The C=N imine bond distances are in the range 1.276 (2)-1.279 (2) A and the C=N-C bond angles are in the range 123.05 (16)-124.64 (17) degrees . The configurations about the C=N bonds are anti (1E).
