Figure 1
The structures of compounds 1–6, showing the copper dimer units and the atom-labelling schemes. For clarity, the labels of the C and H atoms are not shown. Displacement ellipsoids are drawn at the 50% probability level. H atoms are represented by spheres of arbitrary size. The red dotted lines represent hydrogen-bonding interactions. In 2, only one configuration of the disordered dioxane molecules is shown, and in 4, only one configuration of the DABCO molecules is shown. |
