6. 3L (28 mg, 0.075 mmol) and triethylamine (92 mg. 0.91 mmol) were successively added. The mixture was stirred and filtered; a slow evaporation gave dark brown plates.
7. w=0.062. Intensity data were collected on an Enraf-Nonius CAD4 diffractometer using graphile-monochromated Mo-Kα radiation. All the structures were solved by the direct method and refined by the full-matrix least-squares method using a MoIEN program package.
