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^)+(0.0558P)^2^+3.6994P] 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 754 _refine_ls_number_parameters 62 _refine_ls_number_restraints 4 _refine_ls_R_factor_all 0.0631 _refine_ls_R_factor_gt 0.0433 _refine_ls_wR_factor_ref 0.1234 _refine_ls_wR_factor_gt 0.1051 _refine_ls_goodness_of_fit_ref 0.932 _refine_ls_restrained_S_all 0.929 _refine_ls_shift/su_max 1.622 _refine_ls_shift/su_mean 0.377 loop_ _atom_site_label _atom_site_type_symbol _atom_site_thermal_displace_type _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_occupancy _atom_site_U_iso_or_equiv _atom_site_calc_flag _atom_site_refinement_flags Si Si Uani 0.57468(16) 0.16691(9) 0.22461(11) 0.710 0.0165(3) . .
