Figure 3
Extract of molecular structures from X-ray diffraction analysis, showing the seven-membered-ring chelates of (a) [Rh(BICP)(cod)]BF4, (II) (pronounced deviation from skew conformation), and (b) [Rh(BINAP)(thf)2]BF4 (thf is tetrahydrofuran; skew conformation) (Preetz et al., 2011). The figure was prepared using SCHAKAL (Keller & Pierrard, 1999). |
