10. 2 = 0.2425 for all reflections. The crystal structure (1) was solved by direct methods using SHELX-97 (Sheldrich, G. M. University of Gottingen: Gottingen, Germany, 1990) and expanded using difference Fourier techniques, refined by SHELX-97 (Sheldrich, G. M. 1997). Crystallographic data for the structure of 1 have been deposited in the Cambridge Crystallographic Data Centre (deposition number: CCDC-684851).
