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

The title Schiff base, C(19)H(22)N(2)O(3), 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)°. In the crystal, O—H⋯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⋯O inter­actions and C—H⋯π short contacts, forming a three-dimensional network.
