Long chain primary alcohols (n-alkanols) are known to pack differently to the n-alkanes. A key distinction arises from the asymmetry of the chain end containing the alcohol moiety. The alcohol groups from two chains form hydrogen bonding interactions, driving alcohol-alcohol interactions as a guiding organizational principle for n-alkanol crystallization. Typical packing motifs are described by either a monoclinic γ form (Figure , C2/c unit cell), a "staircase" packing with chain ends offset rather than aligned, 28 or by a monoclinic β form with the chain ends aligned in lamellae but with gauche conformations at the chain ends to accommodate a hydrogen bonding network between the terminal alcohol groups (Figure , P21/c unit cell). Dorset has proposed long chain alcohols may also pack in an orthorhombic β form, with similar structural characteristics to the n-alkanes. We have constructed a P2/c unit cell following the Pbcm structure of the n-alkanes to model these characteristics (Figure ). In the 'down-chain' orientation, all considered structures exhibit packing as in the polyethylene sub-cell, albeit with a variety of displacements akin to differences between the Pbcm and A21am n-alkane unit cells. These structural models, built from previous reports on shorter n-alkanols, provide an overview of the key functional group interactions and resulting packing motifs possible in C30H61OH and in binary mixtures with C31H64.
