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^ > 2\s(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. A total of 85 restraints were applied. These comprise six ISOR restraints on each of the twelve carbon atoms c(1) to C(12) and on atoms Se(1) and Br(1). Additionally, one floating origin restraint was generated due to the P21 (no. 4) space group. ; _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^)+(0.1203P)^2^+28.2540P] where P=(Fo^2^+2Fc^2^)/3' _refine_ls_hydrogen_treatment constr _refine_ls_extinction_method SHELXL _refine_ls_extinction_expression Fc^*^=kFc[1+0.001xFc^2^\l^3^/sin(2\q)]^-1/4^ _refine_ls_extinction_coef 0.003(2) _refine_ls_number_reflns 2061 _refine_ls_number_parameters 147 _refine_ls_number_restraints 85 _refine_ls_R_factor_all 0.1222 _refine_ls_R_factor_gt 0.0886 _refine_ls_wR_factor_ref 0.2544 _refine_ls_wR_factor_gt 0.213 _refine_ls_goodness_of_fit_ref 1.068 _refine_ls_restrained_S_all 1.048 _refine_ls_shift/su_max 0.004 _refine_ls_shift/su_mean 0 _refine_ls_abs_structure_details 'Flack H D (1983), Acta Cryst.

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^ > 2\s(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.

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^ > 2\s(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.
