22. 3. Of the 103 43 reflections collected (2θ = 3.04-50°), 5053 reflections were considered as observed [I > 2σ(I)] and were corrected for Lorentz, polarization and absorption effects (G.M. Sheldrick, SADABS, Program for Empirical Absorption Correction of Area Detector Data, University Göttingen, Germany, 2003). The structures were solved by direct methods, and refined by full-matrix least-squares techniques using SHELXTL (G.M. Sheldrick, SHELXL, Version 5.1, Bruker Analytical X-ray Systems, Madison, WI, 1997). All non-H atoms were refined anisotropically. The final refinements converged at R1 = 0.0418, wR2 = 0.0857, and GOF = 1.523
