all reflections (Table 5).[38] All non-hydrogen atoms were assigned
anisotropic displacement parameters and refined without posi-
tional constraints, except that the carbon atoms of the toluene mol-
ecule in 6·0.5 toluene were refined isotropically. Hydrogen atoms
were constrained to ideal geometries and refined with fixed iso-
tropic displacement parameters. Refinement proceeded smoothly to
give the residuals shown in Table 5. Complex neutral-atom scat-
tering factors were used.[39] CCDC-221232 (for 1f), -221233 (for
4b) and -221234 (for 6·0.5 toluene) contain the supplementary crys-
tallographic data for this paper. These data can be obtained free
