10. Diffraction data were collected for 1 and 2 also at 275 K. Comparison of the refined parameters at 275 K with those at 100 K, showed a significant increase in the thermal parameters essentially of the side chains, but their order is maintained. A similar influence of the temperature was observed when the AdoCbl structures, determined at 279 and 15 K, were compared. 11 Only slight differences in the esd's of the coordination geometry were detectable at the two temperatures. A shrinkage of about 3% in the unit cell determined at the lowest temperature is found. Diffraction data for 2 at room temperature were also collected using a conventional X-ray source (Mo Kα). A detailed comparison of the five data collections will be given elsewere.
