However, these could not be accurately identified and could not be modeled either by parts or by partial occupancies or by fixing atomic distances. SQUEEZE was therefore applied to enable the refinement to proceed. 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^ > 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^)+(0.0502P)^2^+42.5622P] 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 constr _refine_ls_extinction_method none _refine_ls_extinction_coef ? _refine_ls_number_reflns 5587 _refine_ls_number_parameters 307 _refine_ls_number_restraints 0 _refine_ls_R_factor_all 0.0565 _refine_ls_R_factor_gt 0.0516 _refine_ls_wR_factor_ref 0.1288 _refine_ls_wR_factor_gt 0.1263 _refine_ls_goodness_of_fit_ref 1.168 _refine_ls_restrained_S_all 1.168 _refine_ls_shift/su_max 0.000 _refine_ls_shift/su_mean 0.000 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 U001 U 0.16570(3) 0.102624(13) 0.69039(2) 0.01299(12) Uani 1 1 d . . .
