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. ; _refine_diff_density_max 0.273 _refine_diff_density_min -0.328 _refine_diff_density_rms 0.102 _refine_ls_extinction_coef 0.086(3) _refine_ls_extinction_expression Fc^*^=kFc[1+0.001xFc^2^\l^3^/sin(2\q)]^-1/4^ _refine_ls_extinction_method 'SHELXL-2018/1 (Sheldrick 2018)' _refine_ls_goodness_of_fit_ref 1.121 _refine_ls_hydrogen_treatment mixed _refine_ls_matrix_type full _refine_ls_number_parameters 228 _refine_ls_number_reflns 3837 _refine_ls_number_restraints 0 _refine_ls_restrained_S_all 1.121 _refine_ls_R_factor_all 0.0458 _refine_ls_R_factor_gt 0.0449 _refine_ls_shift/su_max 0.000 _refine_ls_shift/su_mean 0.000 _refine_ls_structure_factor_coef Fsqd _refine_ls_weighting_details 'w=1/[\s^2^(Fo^2^)+(0.0724P)^2^+0.2534P] where P=(Fo^2^+2Fc^2^)/3' _refine_ls_weighting_scheme calc _refine_ls_wR_factor_gt 0.1177 _refine_ls_wR_factor_ref 0.1189 _refine_special_details ; 1.
