In Sorangicin A,
the C16-C17-C18-C19 moeity is disordered by rotation about the C14-C15 and C19-C20 bonds. Click "animate" to see the structure flip between the two disorder contributions.
This rotational degree of freedom leads to the disordered structure shown here:
It may be instructive to represent the atoms in the disordered moiety with van der Waal's radii (click on "VDW").
