Pyridine-2,6-dimethanol, C7H9NO2, forms a chain structure in which the
molecules are linked by O-H ... O hydrogen bonds into dimeric units l
ying across centres of inversion, these dimers being linked by O-H ...
N hydrogen bonds into chains around other centres of inversion. In th
e structure of benzene-1,3,5-trimethanol, C9H12O3, the molecules form
a continuous three-dimensional network in which each molecule is hydro
gen-bonded to six others.
