Weighted R-factors wR and all goodnesses 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 observed criterion of F^2^ > 2sigma(F^2^) is used only for calculating _R_factor_obs 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 w=1/[\s^2^(Fo^2^)+(0.1044P)^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 ? _refine_ls_extinction_method none _refine_ls_extinction_coef ? _refine_ls_number_reflns 3140 _refine_ls_number_parameters 181 _refine_ls_number_restraints 0 _refine_ls_R_factor_all 0.1109 _refine_ls_R_factor_obs 0.0540 _refine_ls_wR_factor_all 0.1759 _refine_ls_wR_factor_obs 0.1482 _refine_ls_goodness_of_fit_all 0.979 _refine_ls_goodness_of_fit_obs 1.152 _refine_ls_restrained_S_all 0.979 _refine_ls_restrained_S_obs 1.152 _refine_ls_shift/esd_max 0.000 _refine_ls_shift/esd_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_thermal_displace_type _atom_site_occupancy _atom_site_calc_flag _atom_site_refinement_flags _atom_site_disorder_group S1A S 0.60649(8) -0.1910(2) 0.27476(7) 0.0807(4) Uani 1 d . .

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. ; loop_ _geom_bond_atom_site_label_1 _geom_bond_atom_site_label_2 _geom_bond_distance _geom_bond_site_symmetry_2 _geom_bond_publ_flag S1A C5A 1.662(6) . ?
