Reaction of L8 (19.8 mg, 0.05 mmol) in acetonitrile with silver
tetrafluoroborate (32.1 mg, 0.16 mmol) in acetonitrile gave a
colourless solution. A fawn precipitate appeared on diffusion of
pentane into this solution. Yield 28.7 mg (95 %), mp 185–1878C

Ka (l ¼ 0.71073 A) radiation at the temperature indicated in the
following table. The data reduction was performed using
SAINT.[30] Intensities were corrected for Lorentz and polarisa-
tion effects and for absorption using SADABS.[31] Space groups
were determined from systematic absences and checked for
higher symmetry. The structures were solved by direct methods
using SHELXS,[32] and refined on F2 using all data by full-matrix
least-squares procedures with SHELXL-97.[33] All non-
hydrogen atoms were refined with anisotropic displacement
parameters. Hydrogen atoms were included in calculated
positions with isotropic displacement parameters 1.3 times the
isotropic equivalent of their carrier carbons. The functions
