Abstract: In the hydrogen-bonding networks of 8-hydroxy-5-hydroxymethyl-3,6-dioxatricyclo[6.3.1.01.5]dodecan-2-one and 5,7-bis(hydroxymethyl)-3,6-dioxatricyclo[5.3.1.01.5]undecan-2-one, both C11H16O5, layers and double strands, respectively, lead to the formation of chains connected by hydroxy-to-hydroxy contacts, where the hydroxymethyl group, present in both structures, acts as a donor. The secondary structures differ in the hydrogen bonding of these chains via the second hydroxy group, which is involved in hydroxy-to-carbonyl and hydroxy-to-hydroxy bonds, respectively.
Formula: C11H16O5 and C11H16O5

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.
