Intensity data were collected on a Smart-1000 diffractometer with graphite monochromated Mo Kα radiation (λ = 0.71073 Å) using the ω scan mode with 2.04° < 6 θ 25.01°; 4637 unique reflections were measured and 1921 reflections with I > 2σ(I) were used in the Fourier techniques. The final refinement was converged to R = 0.0570 and wR = 0.1140.
