Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

We have isolated and crystallographically characterized the three homologous compounds N,N'-bis(2-methoxy­benzyl­idene)­ethane-1,2-di­amine (MeSalen), C18H20N2O2, N,N'-bis(2-methoxy­benzyl­idene)­propane-1,3-di­amine (MeSalpr), C19H22N2O2, and N,N'-bis(2-methoxy­benzyl­idene)­butane-1,4-di­amine (MeSalbu), C20H24N2O2. In contrast with MeSalpr, the mol­ecules of MeSalen and MeSalbu, which have an even number of methyl­ene units, have crystallographic symmetry. Comparing these methoxy-substituted species with their hydroxy equivalents shows that the aryl rings rotate upon removal of the O - HN hydrogen bonds. The packing of MeSalen and MeSalpr is controlled by C - Hπ interactions, whereas that of MeSalbu has only van der Waals contacts.
