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. ; _refine_ls_structure_factor_coef Fsqd _refine_ls_matrix_type full _refine_ls_weighting_scheme calc _refine_ls_weighting_details 'calc w=1/[\s^2^(Fo^2^)+(0.0650P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3' _atom_sites_solution_primary direct _atom_sites_solution_secondary difmap _atom_sites_solution_hydrogens geom _refine_ls_hydrogen_treatment mixed _refine_ls_extinction_method none _refine_ls_extinction_coef ? _refine_ls_number_reflns 5307 _refine_ls_number_parameters 424 _refine_ls_number_restraints 0 _refine_ls_R_factor_all 0.0916 _refine_ls_R_factor_gt 0.0683 _refine_ls_wR_factor_ref 0.1769 _refine_ls_wR_factor_gt 0.1630 _refine_ls_goodness_of_fit_ref 1.698 _refine_ls_restrained_S_all 1.698 _refine_ls_shift/su_max 0.025 _refine_ls_shift/su_mean 0.003 loop_ _atom_site_label _atom_site_type_symbol _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_U_iso_or_equiv _atom_site_adp_type _atom_site_occupancy _atom_site_symmetry_multiplicity _atom_site_calc_flag _atom_site_refinement_flags _atom_site_disorder_assembly _atom_site_disorder_group Co1 Co 0.27399(3) 0.43725(6) 0.30348(3) 0.0278(2) Uani 1 1 d . . .
