 Refinement of F^2^ against ALL reflections.  The weighted R-factor wR and 
 goodness of fit S are based on F^2^, conventional R-factors R are based 
 on F, with F set to zero for negative F^2^. The threshold expression of 
 F^2^ > 2sigma(F^2^) is used only for calculating R-factors(gt) etc. and is 
 not relevant to the choice of reflections for refinement.  R-factors based 
 on F^2^ are statistically about twice as large as those based on F, and R- 
 factors based on ALL data will be even larger. 

 Several low angles reflections were omitted due to beam stop shadowing
 effects.

 Three of the molecules were partial racemates. The racemic disordered
 refined to 0.957(6)/0.043(6) for molecule B, 0.766(5)/0.234(5) for
 molecule C and 0.808(4)/0.192(4) for molecule D. The anisotropic 
 displacement parameters for the disordered chiral C atom (C9) were
 constrained to be the same as the were in close proximity (<0.5A).
 For molecules B, C, D the C8-C9 and C8-C9' distances were restrained
 to be the same as were the C10-C9 and C10-C9' distances and the
 C9-F2 and C9'-F2'. For the disordered molecules U(iso)F9' was set
 to U(aniso,eq)F2.

 All esds (except the esd in the dihedral angle between two l.s. planes) 
 are estimated using the full covariance matrix.  The cell esds are taken 
 into account individually in the estimation of esds in distances, angles 
 and torsion angles; correlations between esds in cell parameters are only 
 used when they are defined by crystal symmetry.  An approximate (isotropic) 
 treatment of cell esds is used for estimating esds involving l.s. planes.
