Abstract: Structure analyses of 4,4'-bis(4-hydroxybutyl)-2,2'-bipyridine, C18H24N2O2, (I), and 4,4'-bis(4-bromobutyl)-2,2'-bipyridine, C18H22Br2N2, (II), reveal intermolecular hydrogen bonding in both compounds. For (I), O-H
N intermolecular hydrogen bonding leads to the formation of an infinite two-dimensional polymer, and ![[bold pi]](/logos/entities/pi_bdgif.gif)
stacking interactions are also observed. For (II), C-HN intermolecular hydrogen bonding leads to the formation of a zigzag polymer. The two compounds crystallize in different crystal systems, but both molecules possess Ci symmetry, with one half molecule in the asymmetric unit.
Formula: C18H24N2O2 and C18H22Br2N2

If the supplementary material that you require is not shown in the list above, it may only be available in our hard-copy archive. However, our policy is to progressively digitize old hard-copy supplementary documents where possible.
Please help us to work towards this goal by completing the form below. This will register your wish to receive a supplementary document, which we shall scan to create a PDF and then make available via the web to you and to other requestors in the future.
