Figure 4
A superposition of the molecular conformations of (I) and (II), along with the respective optimized structures, (Io) and (IIo). The overlay was made by making a least-squares fit through the benzene ring of (I). The r.m.s. deviations (Å) with respect to the conformation of (I) (orange in the electronic version of the journal) are: (II) 0.008 (red), (Io) 0.012 (green) and (IIo) 0.011 (cyan). |
