Figure 2
Perspective drawings of dimer ribbons formed by two vic-diols. The H atoms are shown for the hydroxyl groups only. All non-H atoms have been deleted except for those directly attached to the (HO)CC(OH) unit. (a) Dimer ribbon of rac-1,2-cyclohexanediol as it would appear in a completely ordered, triclinic crystal of the 1:1 compound of rac-1,2-CHD and triphenylphosphine oxide. (b) Dimer ribbon of rac-1,2-CHD as it would appear in a completely disordered, monoclinic crystal of the 1:1 compound of rac-1,2-CHD and triphenylphosphine oxide. (c) Dimer ribbon of rac-1,2-dicyclohexylethane-1,2-diol (C2/c, Z′ = 1; Patrick & Brock, 2006  ). A comparison of the ribbons in (a) and (c) shows that the R44(8) hydrogen-bonded rings are much more square in the latter, but are also alternately displaced towards the two sides of the ribbon, i.e. along b. |
