24. Data collection. The unit cell and intensity data were collected on a Bruker-Nonius diffractometer. 5454 reflections were collected, of which 2925 [R(int) = 0.0489]were independent reflections, with the 2θ range for data collection of 2.28 to 24.99°.
25. Structure Solution and Refinement: Structure solution and refinement were achieved using SHELX97 and SHELXL97. Full matrix least squares on F2 of data converged to R1=0.0437, wR2=0.0841 [I>2σI]. Atomic coordinates, bond lengths, angles and thermal parameters have been deposited at the Cambridge Crystallographic Data Center, deposition number CCDC 635098.
