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^ > 2sigma(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. ; _reflns_number_total 7884 _reflns_number_gt 5876 _reflns_threshold_expression >2sigma(I) _refine_ls_structure_factor_coef Fsqd _refine_ls_matrix_type full _refine_ls_R_factor_all 0.0634 _refine_ls_R_factor_gt 0.0452 _refine_ls_wR_factor_gt 0.1280 _refine_ls_wR_factor_ref 0.1445 _refine_ls_goodness_of_fit_ref 0.977 _refine_ls_restrained_S_all 0.977 _refine_ls_number_reflns 7884 _refine_ls_number_parameters 313 _refine_ls_number_restraints 0 _refine_ls_hydrogen_treatment constr _refine_ls_weighting_scheme calc _refine_ls_weighting_details 'calc w=1/[\s^2^(Fo^2^)+(0.0814P)^2^+5.8529P] where P=(Fo^2^+2Fc^2^)/3' _atom_sites_solution_hydrogens geom _atom_sites_solution_primary direct _atom_sites_solution_secondary difmap _refine_ls_shift/su_max 0.000 _refine_ls_shift/su_mean 0.000 _refine_diff_density_max 1.464 _refine_diff_density_min -1.041 _refine_ls_extinction_method none _refine_ls_extinction_coef ? loop_ _atom_type_symbol _atom_type_description _atom_type_scat_dispersion_real _atom_type_scat_dispersion_imag _atom_type_scat_source C C 0.0033 0.0016 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' H H 0.0000 0.0000 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' N N 0.0061 0.0033 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' F F 0.0171 0.0103 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' P P 0.1023 0.0942 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' Ru Ru -1.2594 0.8363 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' _computing_data_collection 'Bruker Instrument Service v2010.7.0.0' _computing_cell_refinement 'SAINT V7.68A (Bruker AXS, 2009)' _computing_data_reduction 'SAINT V7.68A (Bruker AXS, 2009)' _computing_structure_solution 'SHELXS-97 (Sheldrick, 2008)' _computing_structure_refinement 'SHELXL-97 (Sheldrick, 2008)' _computing_molecular_graphics ? _computing_publication_material ? loop_ _atom_site_type_symbol _atom_site_label _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_U_iso_or_equiv _atom_site_adp_type _atom_site_calc_flag _atom_site_refinement_flags _atom_site_occupancy _atom_site_disorder_assembly _atom_site_disorder_group Ru Ru1 0.5 0.446685(14) 0.25 0.01917(7) Uani d S 1 . .
