REFINEMENT DATA _refine_special_details ; The refinement was carried out against all reflections. The conventional R-factor is always based on F. The goodness of fit as well as the weighted R-factor are based on F and F^2^ for refinement carried out on F and F^2^, respectively. The threshold expression is used only for calculating R-factors etc. and it is not relevant to the choice of reflections for refinement. The program used for refinement, Jana2006, uses the weighting scheme based on the experimental expectations, see _refine_ls_weighting_details, that does not force S to be one. Therefore the values of S are usually larger than the ones from the SHELX program. ; _reflns_number_total 18342 _reflns_number_gt 14164 _reflns_threshold_expression I>3\s(I) _refine_ls_structure_factor_coef Fsqd _refine_ls_R_factor_gt 0.0301 _refine_ls_wR_factor_gt 0.0826 _refine_ls_R_factor_all 0.0462 _refine_ls_wR_factor_all 0.0892 _refine_ls_goodness_of_fit_all 1.33 _refine_ls_goodness_of_fit_gt 1.41 _refine_ls_wR_factor_ref 0.0892 _refine_ls_goodness_of_fit_ref 1.33 _refine_ls_restrained_S_gt ? _refine_ls_restrained_S_all ? _refine_ls_number_reflns 18342 _refine_ls_number_parameters 620 _refine_ls_number_restraints 2 _refine_ls_number_constraints 365 _refine_ls_weighting_scheme sigma _refine_ls_weighting_details w=1/(\s^2^(I)+0.0016I^2^) _refine_ls_hydrogen_treatment constr _refine_ls_shift/su_max 0.0196 _refine_ls_shift/su_mean 0.0004 _refine_diff_density_max 1.00 _refine_diff_density_min -1.02 _refine_ls_extinction_method none _refine_ls_extinction_coef ? _refine_ls_abs_structure_details ? _refine_ls_abs_structure_Flack ? _refine_ls_abs_structure_Rogers ? loop_ _atom_type_symbol _atom_type_scat_dispersion_real _atom_type_scat_dispersion_imag _atom_type_scat_source C 0.0033 0.0016 'International Tables Vol C tables 4.2.6.8 and 6.1.1.1' H 0.0000 0.0000 'International Tables Vol C tables 4.2.6.8 and 6.1.1.1' Br -0.2901 2.4595 'International Tables Vol C tables 4.2.6.8 and 6.1.1.1' F 0.0171 0.0103 'International Tables Vol C tables 4.2.6.8 and 6.1.1.1' Mo -1.6832 0.6857 'International Tables Vol C tables 4.2.6.8 and 6.1.1.1' N 0.0061 0.0033 'International Tables Vol C tables 4.2.6.8 and 6.1.1.1' O 0.0106 0.0060 'International Tables Vol C tables 4.2.6.8 and 6.1.1.1' _computing_data_collection ; CrysAlisPro (Agilent Technologies, 2010) ; _computing_cell_refinement CrysalisPro _computing_data_reduction CrysalisPro _computing_structure_solution 'SIR2002 (Burla et al., 2003)' _computing_structure_refinement "Jana2006 (Pet\
