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^ > \s(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. ; _reflns_number_total 3864 _reflns_number_gt 2815 _reflns_threshold_expression I>2\s(I) _refine_ls_structure_factor_coef Fsqd _refine_ls_matrix_type full _refine_ls_R_factor_all 0.0619 _refine_ls_R_factor_gt 0.0394 _refine_ls_wR_factor_gt 0.0872 _refine_ls_wR_factor_ref 0.0989 _refine_ls_goodness_of_fit_ref 1.018 _refine_ls_restrained_S_all 1.064 _refine_ls_number_reflns 3864 _refine_ls_number_parameters 291 _refine_ls_number_restraints 54 _refine_ls_hydrogen_treatment constr _refine_ls_weighting_scheme calc _refine_ls_weighting_details 'calc w = 1/[\s^2^(Fo^2^)+(0.0455P)^2^+0.4335P] where P=(Fo^2^+2Fc^2^)/3' _atom_sites_solution_hydrogens geom _atom_sites_solution_primary direct _atom_sites_solution_secondary difmap _refine_ls_shift/su_max 0.001 _refine_ls_shift/su_mean 0.000 _refine_diff_density_max 0.326 _refine_diff_density_min -0.352 _refine_ls_extinction_method none _refine_ls_extinction_coef ? loop_ _atom_type_symbol _atom_type_description _atom_type_scat_dispersion_real _atom_type_scat_dispersion_imag _atom_type_scat_source 'C' 'C' 0.0033 0.0016 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' 'H' 'H' 0.0000 0.0000 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' 'N' 'N' 0.0061 0.0033 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' 'O' 'O' 0.0106 0.0060 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' 'Na' 'Na' 0.0362 0.0249 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' 'Ni' 'Ni' 0.3393 1.1124 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' _computing_data_collection 'APEX2 (Bruker, 2004)' _computing_cell_refinement 'SAINT-Plus (Bruker, 2001)' _computing_data_reduction 'SAINT-Plus (Bruker, 2001)' _computing_structure_solution 'SHELXS97 (Sheldrick, 2008)' _computing_structure_refinement 'SHELXL97 (Sheldrick, 2008)' _computing_molecular_graphics 'SHELXTL (Sheldrick, 2008)' _computing_publication_material 'SHELXTL (Sheldrick, 2008)' loop_ _atom_site_type_symbol _atom_site_label _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_U_iso_or_equiv _atom_site_adp_type _atom_site_calc_flag _atom_site_refinement_flags _atom_site_occupancy _atom_site_disorder_assembly _atom_site_disorder_group Ni Ni1 0.24893(5) 0.506776(16) 0.06029(3) 0.04684(15) Uani d . 1 . .
