4. (a) The data were collected using a Siemens 3 circle diffractometer equipped with a SMART CCD area detector, graphite-monochromated Mo Kα radiation. Anisotropic thermal parameters were used for all non-H atoms. Hydrogen atoms were inserted at calculated positions and fixed. The structure was solved by direct methods using SHELXTL5(b)version 5.0, and the refinements were carried out using SHELXTL965(c)software, minimizing on the weightedRfactor wR2. Residuals were calculated using the following formulas: R= ∑|Fo−Fc/∑Fo(forFo≥ 4σ(Fo)),(wR2 = [∑[w(Fo2−Fc2)2]/∑[w(Fo2)2]]1/2for all data); a weighting scheme of the formw-1= σ2(Fo2) +aP+bPwas used, whereP= [max(Fo2, 0) + 2Fc2]/3, where max(Fo2, 0) indicates that the larger ofFo2or 0 is taken,aandbare values set by the program. All non-H atoms were anisotropic. Additional material is available from the Cambridge Crystallographic Data Centre {117980}. Atom positions were refined, andUiso(H) = 1.5Ueq(C).
