For 8529 unique observed reflections (I > 2σ(I)) collected at T = 133 K on a Rigaku AFC6S diffractometer (5 < 2θ < 50°) and corrected for absorption the final R is 0.061 (wR2 = 0.165 for the 9825 reflections having I > 0 used in the refinement). All calculations were carried out on a Quansan Personal Computer equipped with an Intel Pentium processor.
