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