2016 observations (of 3010 unique data). The diol O atoms form a gauche interaction with O-CC -O torsion angle, 42.5 (3) ° , smaller than that in related compounds. Both intramolecular and intermolecular hydrogen bonding are present. lntroduetlon. During the course of our studies preparing stilbene cycles as backbones for intramolecular reactions (Tirado-Rives, Oliver, Fronczek & Gandour, 1984), the title compound has been isolated and its crystal structure has been determined.
