The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 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 基于F2的结构精修_refine_ls_matrix_type full精修矩阵类型_refine_ls_weighting_scheme calc 权重方案_refine_ls_weighting_details 权重方案表达式 calc w=1/s2(Fo2)+(0.0546P)2 where P=(Fo2+2Fc2)/3 _atom_sites_solution_primary direct解析粗结构的方法_atom_sites_solution_secondary difmap进一步解析结构的方法_atom_sites_solution_hydrogens geom获得氢原子的方法_refine_ls_hydrogen_treatment mixed结构精修中氢原子的处理方法_refine_ls_extinction_method none消光校正方案_refine_ls_extinction_coef 消光校正系数_refine_ls_number_reflns 2995参加结构精修的衍射点数 23a_refine_ls_number_parameters 244参加结构精修的参数数目 23c_refine_ls_number_restraints 0结构精修中几何限制数目 23b_refine_ls_R_factor_all 0.0641对全部衍射点的R1值 26a_refine_ls_R_factor_gt 0.0475对可观察衍射点的R1值 25a_refine_ls_wR_factor_ref 0.1071对全部衍射点的wR2值 26b_refine_ls_wR_factor_gt 0.1036对可观察衍射点的wR2值 25b_refine_ls_goodness_of_fit_ref 1.058对可观察衍射点的S值 24_refine_ls_restrained_S_all 1.058对全部衍射点的S值_refine_ls_shift/su_max 0.000最后精修过程的漂移值_refine_ls_shift/su_mean 0.000最后精修过程的平均漂移值 loop_ 结构中各原子坐标, 各向同性振动参数, 原子占有率等 _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 0.2152(5) 0.44531(17) 0.5109(4) 0.0230(7) Uani 1 1 d . . .

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_ 分子中原子间键长列表 _geom_bond_atom_site_label_1 _geom_bond_atom_site_label_2 _geom_bond_distance _geom_bond_site_symmetry_2 _geom_bond_publ_flag C1 O2 1.220(4) . ?
