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

In the title compound, C17H18N2O, the central carbon atom with the OH substituent and one of the (E)-benzylideneamino substituents are disordered over two sets of sites with occupancies of 0.851 (4) and 0.149 (4). The relative positions of the two disorder components is equivalent to a rotation of approximately 60 degrees about the C-N single bond. In the crystal, the molecules are held together by O-H center dot center dot center dot N hydrogen bonds, forming simple C(5) chains along the b-axis direction. In addition, pairs of the chains are further aggregated by weak C-H center dot center dot center dot pi interactions.
