Crystal structure of 1,3-bis[(E)-4-methoxybenzylideneamino]propan-2-ol

The title Schiff base, C19H22N2O3, was synthesized via the condensation reaction of 1,3-diaminopropan-2-ol with 4-methoxybenzaldehyde using water as solvent. The molecule exists in an E,E conformation with respect to the C=N imine bonds and the dihedral angle between the aromatic rings is 37.25 (15)degrees. In the crystal, O-H center dot center dot center dot N hydrogen bonds link the molecules into infinite C(5) chains propagating along the a-axis direction. The packing of these chains is consolidated by C-H center dot center dot center dot O interactions and C-H center dot center dot center dot pi short contacts, forming a three-dimensional network.
