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^)+(0.0472P)^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 constr _refine_ls_extinction_method none _refine_ls_number_reflns 6958 _refine_ls_number_parameters 392 _refine_ls_number_restraints 0 _refine_ls_R_factor_all 0.0894 _refine_ls_R_factor_gt 0.0475 _refine_ls_wR_factor_ref 0.1105 _refine_ls_wR_factor_gt 0.0983 _refine_ls_goodness_of_fit_ref 0.877 _refine_ls_restrained_S_all 0.877 _refine_ls_shift/su_max 0.05 _refine_ls_shift/su_mean 0.001 _refine_diff_density_max 0.619 _refine_diff_density_min -0.464 _refine_diff_density_rms 0.077 #----------------------------------------------------------------------------# # ATOMIC TYPES, COORDINATES AND THERMAL PARAMETERS # #----------------------------------------------------------------------------# 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 0 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' B B 0.0013 0.0007 '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' Cl Cl 0.1484 0.1585 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' Nb Nb -2.0727 0.6215 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' 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 C1 C -0.0494(4) 0.10125(19) 0.4658(3) 0.0524(12) Uani 1 1 d . . .
