Figure 3
A view illustrating the second crystallographically independent iodonium ion in (II), the nearby trifluoromethanesulfonate ions and the cyclic unit thereby formed. Double-primed atoms are related to unprimed atoms via the crystallographic inversion center (,0,). Note that there are no interactions between this iodonium ion and the trifluoromethanesulfonate counter-ion associated with the other iodonium ion, or vice versa (Fig. 2). Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. |
