24. The data set for 3b was collected with Enraf Nonius CAD4 and Nonius KappaCCD diffractometers, in case of Mo radiation equipped with a rotating anode generator. Programs used: data collection EXPRESS (Nonius B.V., 1994) and COLLECT (Nonius B.V., 1998), data reduction MolEN (K. Fair, Enraf- Nonius B.V., 1990) and Denzo-SMN (Z. Otwinowski, W Minor, Methods Enzymol. 1997, 276, 307-326) and Denzo (Z. Otwinowski, D. Borek, W. Majewski, W. Minor, Acta Crys- tallogr., Sect. A 2003, 59, 228-234), structure solution SHELXS-97 (G. M. Sheldrick, Acta Crystallogr., Sect. A 1990, 46, 467-473), structure refinement SHELXL-97 (G. M. Sheldrick, Acta Crystallogr., Sect. A 2008, 64, 112-122), graphics

26. CCDC-713888 (for 3b), -713889 (for 5b) and -713890 (for 5k) contain the supplementary crystallographic data for this paper. These data can be obtained free of charge from The Cambridge Crystallographic Data Centre via www.ccdc.cam.ac.uk/data-request/cif.
27. Intensity data for 5b and 5k were collected at 123 K with a Rigaku Single Crystal CCD X-ray Diffractometer Saturn 7 with MicroMax 7 with Mo-Ka radiation (X = 0.71070 A)and graphite monochromator. The structure was solved by direct methods (SHELXS-97) and refined by the full-matrix least-squares on F2 (SHELXL-97).
