These intensities were corrected for absorption effects by using a multi-scan method (SADABS, Bruker 2001). Structure solution by direct methods in the Cmcm space group, followed by refinement of atomic coordinates and anisotropic thermal parameters, were performed using respectively the SHELXS-97 and SHELXL-97 programs (Sheldrick, 2008). ; _diffrn_ambient_temperature 293 _diffrn_radiation_type MoK\a _diffrn_radiation_wavelength 0.71073 _diffrn_radiation_source 'fine-focus sealed tube' _diffrn_radiation_monochromator graphite _diffrn_measurement_device_type 'Nonius KappaCCD' _diffrn_measurement_method 'CCD' _diffrn_detector_area_resol_mean 9 _diffrn_reflns_number 3335 _diffrn_reflns_av_R_equivalents 0.0211 _diffrn_reflns_av_sigmaI/netI 0.0117 _diffrn_reflns_theta_min 4.92 _diffrn_reflns_theta_max 29.99 _diffrn_reflns_theta_full 29.99 _diffrn_measured_fraction_theta_max 0.997 _diffrn_measured_fraction_theta_full 0.997 _diffrn_reflns_limit_h_min -9 _diffrn_reflns_limit_h_max 9 _diffrn_reflns_limit_k_min -10 _diffrn_reflns_limit_k_max 10 _diffrn_reflns_limit_l_min -10 _diffrn_reflns_limit_l_max 10 _diffrn_standards_number ? _diffrn_standards_interval_count ? _diffrn_standards_interval_time ? _diffrn_standards_decay_% ? _refine_special_details ; 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. ; _reflns_number_total 312 _reflns_number_gt 303 _reflns_threshold_expression I>2\s(I) _refine_ls_structure_factor_coef Fsqd _refine_ls_matrix_type full _refine_ls_R_factor_all 0.0105 _refine_ls_R_factor_gt 0.0098 _refine_ls_wR_factor_gt 0.0230 _refine_ls_wR_factor_ref 0.0233 _refine_ls_goodness_of_fit_ref 0.745 _refine_ls_restrained_S_all 0.745 _refine_ls_number_reflns 312 _refine_ls_number_parameters 22 _refine_ls_number_restraints 0 _refine_ls_weighting_scheme calc _refine_ls_weighting_details 'calc w = 1/[\s^2^(Fo^2^)+(0.0157P)^2^+2.0799P] where P=(Fo^2^+2Fc^2^)/3' _atom_sites_solution_primary direct _atom_sites_solution_secondary difmap _refine_ls_shift/su_max 0.000 _refine_ls_shift/su_mean 0.000 _refine_diff_density_max 0.403 _refine_diff_density_min -0.571 _refine_ls_extinction_method 'SHELXL97 (Sheldrick, 2008)' _refine_ls_extinction_coef 0.0188(6) _refine_ls_extinction_expression 'Fc^*^=kFc[1+0.001xFc^2^\l^3^/sin(2\q)]^-1/4^' loop_ _atom_type_symbol _atom_type_description _atom_type_scat_dispersion_real _atom_type_scat_dispersion_imag _atom_type_scat_source 'F' 'F' 0.0171 0.0103 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' 'I' 'I' -0.4742 1.8119 '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' 'O' 'O' 0.0106 0.0060 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' _computing_data_collection 'COLLECT (Nonius, 1998)' _computing_cell_refinement 'DIRAX/LSQ (Duisenberg, 1992)' _computing_data_reduction 'EvalCCD (Duisenberg

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_site_symmetry_2 _geom_bond_distance _geom_bond_publ_flag I1 O1 10_556 1.7647(17) n I1 O1 . 1.7647(17) y I1 F1 . 2.0040(17) y I1 F1 11_655 2.0040(17) n I1 O1 3 2.8185(19) y I1 O1 2_655 2.8185(19) n Na1 O1 5_445 2.3124(18) y Na1 O1 13 2.3124(18) n Na1 F1 9 2.3627(11) n Na1 F1 . 2.3627(11) y Na1 F1 11 2.3627(11) n Na1 F1 3 2.3627(11) n Na1 Na1 2_554 3.6752(6) n Na1 Na1 2 3.6752(6) n O1 Na1 5 2.3124(18) n F1 Na1 2 2.3627(11) n loop_ _geom_angle_atom_site_label_1 _geom_angle_atom_site_label_2 _geom_angle_atom_site_label_3 _geom_angle_site_symmetry_1 _geom_angle_site_symmetry_3 _geom_angle _geom_angle_publ_flag O1 I1 O1 10_556 . 103.72(12) ?
