Types of hydrogen-bonded ribbons possible for vic-diols. The symbols + and − denote atomic displacements above and below the plane of the drawing. The molecules that form a dimer are homochiral in ribbon types I and III, and heterchiral in ribbon types II and IV. Molecules in the same rail are homochiral in ribbon types I and II, and heterochiral in types III and IV.
