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^)+(0.0569P)^2^+0.2975P] 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_number_reflns 1893 _refine_ls_number_parameters 100 _refine_ls_number_restraints 0 _refine_ls_R_factor_all 0.0368 _refine_ls_R_factor_gt 0.036 _refine_ls_wR_factor_ref 0.0952 _refine_ls_wR_factor_gt 0.0944 _refine_ls_goodness_of_fit_ref 1.111 _refine_ls_restrained_S_all 1.111 _refine_ls_shift/su_max 0 _refine_ls_shift/su_mean 0 _refine_ls_abs_structure_details 'Flack H D (1983), Acta Cryst.

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 Re M1 1.93(4) . ?
