Figure 2 Side view of a centrosymmetric molecular pair (1 - x, -y, 1 - z) showing the sandwiched arrangement of two molecules of the title compound with the hydroxyl group layer located in the middle and the benzyl pendant moieties on the outer surface. Minor components of the disordered tert-butyl groups and H atoms not involved in hydrogen bond interactions have been omitted for clarity. Displacement ellipsoids are plotted at a 50% probability level and H atoms are drawn with an arbitrary radius.  [article HTML]
