Structure solution and Refinement Structure solution program SHELXS-97 (Sheldrick, 2008) Primary solution method Direct methods Secondary solution method Difference Fourier map Hydrogen placement Geometric positions Structure refinement program SHELXL-97 (Sheldrick, 2008) Refinement method Full matrix least-squares on F 2 Data / restraints / parameters 8198 / 0 / 451 Treatment of hydrogen atoms Riding Goodness-of-fit on F 2 1.487 Final R indices [I>2σ(I), 6185 reflections] R1 = 0.0401, wR2 = 0.0514 R indices (all data) R1 = 0.0624, wR2 = 0.0528 Type of weighting scheme used Sigma Weighting scheme used w=1/σ 2 (Fo 2 ) Max shift/error 0.002 Average shift/error 0.000 Largest diff. peak and hole 1.870 and -2.359 e.Å -3 Special Refinement Details Crystals were mounted on a glass fiber using Paratone oil then placed on the diffractometer under a nitrogen stream at 100K. Refinement of F 2 against ALL reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F 2 , conventional R-factors (R) are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > 2σ( F 2 ) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full S292
covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. S293
