The molecule centrosymmetric and nonpolar, its crystal structure noncentrosymmetric and polar! This was the unexpected result of the investigation of the hydroquinone 1 in the solid. Furthermore, 1 contains much larger centrosymmetric, nonpolar subunits, namely, layers with trigonal symmetry held together by strained hydrogen bonds. The polarity of the overall structure arises from the peculiar stacking of these layers.
