The OH bond lengths were restrained to 0.85(4) \%A and the H-O-H angle to 109(4) \%. Other hydrogen atoms were positioned geometrically, the preferred orientations of the methyl groups having been identified previously by examination of the Fourier map. ; #============================================================= _cell_length_a 16.7287(2) _cell_angle_alpha 90 _cell_length_b 13.7692(2) _cell_angle_beta 90 _cell_length_c 20.6788(3) _cell_angle_gamma 90 _cell_volume 4763.17(11) _symmetry_cell_setting Orthorhombic _symmetry_space_group_name_H-M 'P b c a ' loop_ _symmetry_equiv_pos_as_xyz x,y,z -x,-y,-z -x+1/2,y+1/2,z x+1/2,-y+1/2,-z x,-y+1/2,z+1/2 -x,y+1/2,-z+1/2 -x+1/2,-y,z+1/2 x+1/2,y,-z+1/2 loop_ _atom_type_symbol _atom_type_scat_dispersion_real _atom_type_scat_dispersion_imag _atom_type_scat_Cromer_Mann_a1 _atom_type_scat_Cromer_Mann_b1 _atom_type_scat_Cromer_Mann_a2 _atom_type_scat_Cromer_Mann_b2 _atom_type_scat_Cromer_Mann_a3 _atom_type_scat_Cromer_Mann_b3 _atom_type_scat_Cromer_Mann_a4 _atom_type_scat_Cromer_Mann_b4 _atom_type_scat_Cromer_Mann_c _atom_type_scat_source 'C ' 0.0033 0.0016 2.3100 20.8439 1.0200 10.2075 1.5886 0.5687 0.8650 51.6512 0.2156 International_Tables_Vol_IV_Table_2.2B 'H ' 0.0000 0.0000 0.4930 10.5109 0.3229 26.1257 0.1402 3.1424 0.0408 57.7998 0.0030 International_Tables_Vol_IV_Table_2.2B 'N ' 0.0061 0.0033 12.2126 0.0057 3.1322 9.8933 2.0125 28.9975 1.1663 0.5826 -11.5290 International_Tables_Vol_IV_Table_2.2B 'O ' 0.0106 0.0060 3.0485 13.2771 2.2868 5.7011 1.5463 0.3239 0.8670 32.9089 0.2508 International_Tables_Vol_IV_Table_2.2B 'S ' 0.1246 0.1234 6.9053 1.4679 5.2034 22.2151 1.4379 0.2536 1.5863 56.1720 0.8669 International_Tables_Vol_IV_Table_2.2B 'Zn ' 0.2839 1.4301 14.0743 3.2655 7.0318 0.2333 5.1652 10.3163 2.4100 58.7097 1.3041 International_Tables_Vol_IV_Table_2.2B _cell_formula_units_Z 8 _chemical_formula_sum ' C17 H27 N7 O3 S3 Zn1 ' _chemical_formula_moiety ' C15 H21 N7 O2 S2 Zn, C2 H6 O S ' _chemical_compound_source ; synthesis as described ; _chemical_formula_weight 539.02 _cell_measurement_reflns_used 38140 _cell_measurement_theta_min 5 _cell_measurement_theta_max 28 _cell_measurement_temperature 150 _exptl_crystal_description ' fragment ' _exptl_crystal_colour ' orange ' _exptl_crystal_size_min 0.08 _exptl_crystal_size_mid 0.22 _exptl_crystal_size_max 0.32 _exptl_crystal_density_diffrn 1.503 _exptl_crystal_density_meas ? # Non-dispersive F(000): _exptl_crystal_F_000 2240 _exptl_absorpt_coefficient_mu 1.327 _diffrn_measurement_method \w _exptl_absorpt_correction_type multi-scan _exptl_absorpt_process_details ; Denzo/Scalepack (Otwinowski & Minor, 1996) ; _exptl_absorpt_correction_T_min 0.65 _exptl_absorpt_correction_T_max 0.90 _diffrn_standards_interval_time 0 _diffrn_standards_interval_count 0 _diffrn_standards_number 0 _diffrn_standards_decay_% 0.00 _diffrn_ambient_temperature 150 _diffrn_reflns_number 38140 _reflns_number_total 5416 #5972 unique relections including systematic absences _diffrn_reflns_av_R_equivalents 0.054 _diffrn_reflns_theta_min 5.102 _diffrn_reflns_theta_max 27.495 _diffrn_measured_fraction_theta_max 0.998 _diffrn_reflns_theta_full 27.495 _diffrn_measured_fraction_theta_full 0.998 _diffrn_reflns_limit_h_min -21 _diffrn_reflns_limit_h_max 21 _diffrn_reflns_limit_k_min -17 _diffrn_reflns_limit_k_max 17 _diffrn_reflns_limit_l_min -26 _diffrn_reflns_limit_l_max 26 _reflns_limit_h_min 0 _reflns_limit_h_max 21 _reflns_limit_k_min 0 _reflns_limit_k_max 17 _reflns_limit_l_min 0 _reflns_limit_l_max 26 _refine_diff_density_min -0.69 _refine_diff_density_max 1.19 _refine_ls_number_reflns 3547 _refine_ls_number_restraints 5 _refine_ls_number_parameters 300 #_refine_ls_R_factor_ref 0.0406 _refine_ls_wR_factor_ref 0.0471 _refine_ls_goodness_of_fit_ref 1.0465 #_reflns_number_all 5416 _refine_ls_R_factor_all 0.0661 _refine_ls_wR_factor_all 0.0713 # The I/u(I) cutoff below was used for refinement as # well as the _gt R-factors: _reflns_threshold_expression I>3.00u(I) _reflns_number_gt 3547 _refine_ls_R_factor_gt 0.0406 _refine_ls_wR_factor_gt 0.0471 _refine_ls_shift/su_max 0.010690 _refine_ls_structure_factor_coef F _refine_ls_weighting_scheme calc _refine_ls_weighting_details ; Method, part 1, Chebychev polynomial, (Watkin, 1994, Prince, 1982) [weight] = 1.0/[A~0~*T~0~(x)+A~1~*T~1~(x) ... +A~n-1~]*T~n-1~(x)] where A~i~ are the Chebychev coefficients listed below and x= Fcalc/Fmax Method = Robust Weighting (Prince, 1982) W = [weight] * [1-(deltaF/6*sigmaF)^2^]^2^ A~i~ are: 0.682 0.529 0.363 ; _diffrn_radiation_type 'Mo K\a' _diffrn_radiation_wavelength 0.71073 # Uequiv = arithmetic mean of Ui # i.e. Ueqiv = (U1+U2+U3)/3 loop_ _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_occupancy _atom_site_adp_type _atom_site_refinement_flags_posn Zn1 Zn 0.55917(2) 0.38019(3) 0.382067(16) 0.0334 1.0000 Uani D S1 S 0.42693(4) 0.32648(6) 0.40749(4) 0.0367 1.0000 Uani .
