Figure 2
Perspective views of the title complex E–H with the labelling scheme for the cavitand (left) and for the benzonitrile molecules (right; the symmetry code for the guest C1U–C7U/N1U is x, y − 1, z). The ellipsoids are drawn at the 20% probability level. For clarity reasons, only one fourth of the cavitand (E) is labelled. The same scheme is applied to the rest of the macrocycle (F, G and H). Only one orientation of the disordered alkyl chain (H) is shown for clarity. |
