The skeleton of the title molecule, C18H38O2, is all-trans and the molecule
s aggregate to form a layer structure along the c axis as in a smectic C li
quid crystal. The inclination angle of the long axis of the molecule to the
layer plane is the same in each layer, but the direction of the long axis
is opposite in alternate layers. These features are very similar to those o
f the homologues with an even number of C atoms, but different from those w
ith an odd number.
