Therefore, the structure was treated via PLATON/SQUEEZE (van der Sluis & Spek, 1990; Spek, 2003) procedure to remove the contribution of the electron density in the solvent regions from the intensity data, and the solvent-free model was emplyed from the final refinement. The total potential solvent accessible void volume was estimated to be 1376.2 Ang**3 and the electron count per unit cell was 271, which were assigned to 9 acetone molecules per unit cell or 3 acetone molecules per formula unit. ; _audit_creation_method SHELXL-97 _chemical_name_systematic ; ? ; _chemical_name_common ? _chemical_melting_point ? _chemical_formula_moiety 'C45 H90 Na4 O15, 2(Bi2 I12 Pt), 3(C3 H6 O)' _chemical_formula_sum 'C54 H108 Bi4 I24 Na4 O18 Pt2' _chemical_formula_weight 5409.06 loop_ _atom_type_symbol _atom_type_description _atom_type_scat_dispersion_real _atom_type_scat_dispersion_imag _atom_type_scat_source C C 0.0033 0.0016 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' H H 0.0000 0.0000 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' Bi Bi -4.1077 10.2566 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' I I -0.4742 1.8119 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' Na Na 0.0362 0.0249 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' O O 0.0106 0.0060 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' Pt Pt -1.7033 8.3905 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' _symmetry_cell_setting trigonal _symmetry_space_group_name_H-M 'R 32' _symmetry_space_group_name_Hall 'R 3 2"' loop_ _symmetry_equiv_pos_as_xyz 'x, y, z' '-y, x-y, z' '-x+y, -x, z' 'x-y, -y, -z' '-x, -x+y, -z' 'y, x, -z' 'x+2/3, y+1/3, z+1/3' '-y+2/3, x-y+1/3, z+1/3' '-x+y+2/3, -x+1/3, z+1/3' 'x-y+2/3, -y+1/3, -z+1/3' '-x+2/3, -x+y+1/3, -z+1/3' 'y+2/3, x+1/3, -z+1/3' 'x+1/3, y+2/3, z+2/3' '-y+1/3, x-y+2/3, z+2/3' '-x+y+1/3, -x+2/3, z+2/3' 'x-y+1/3, -y+2/3, -z+2/3' '-x+1/3, -x+y+2/3, -z+2/3' 'y+1/3, x+2/3, -z+2/3' _cell_length_a 13.9687(9) _cell_length_b 13.9687(9) _cell_length_c 57.126(8) _cell_angle_alpha 90.00 _cell_angle_beta 90.00 _cell_angle_gamma 120.00 _cell_volume 9653.3(16) _cell_formula_units_Z 3 _cell_measurement_temperature 150(2) _cell_measurement_reflns_used 1658 _cell_measurement_theta_min 2.92 _cell_measurement_theta_max 26.25 _exptl_crystal_description plate _exptl_crystal_colour black _exptl_crystal_size_max 0.24 _exptl_crystal_size_mid 0.20 _exptl_crystal_size_min 0.01 _exptl_crystal_density_meas ? _exptl_crystal_density_diffrn 2.791 _exptl_crystal_density_method 'not measured' _exptl_crystal_F_000 7140 _exptl_absorpt_coefficient_mu 13.427 _exptl_absorpt_correction_type multi-scan _exptl_absorpt_correction_T_min 0.1409 _exptl_absorpt_correction_T_max 0.8774 _exptl_absorpt_process_details SADABS _exptl_special_details ; ? ; _diffrn_ambient_temperature 150(2) _diffrn_radiation_wavelength 0.71073 _diffrn_radiation_type MoK\a _diffrn_radiation_source 'fine-focus sealed tube' _diffrn_radiation_monochromator graphite _diffrn_measurement_device_type 'Bruker Nonius X8Apex CCD area-detector' _diffrn_measurement_method '\f scans' _diffrn_detector_area_resol_mean 25 _diffrn_standards_number 0 _diffrn_reflns_number 7335 _diffrn_reflns_av_R_equivalents 0.0652 _diffrn_reflns_av_sigmaI/netI 0.1053 _diffrn_reflns_limit_h_min -17 _diffrn_reflns_limit_h_max 11 _diffrn_reflns_limit_k_min -12 _diffrn_reflns_limit_k_max 17 _diffrn_reflns_limit_l_min -71 _diffrn_reflns_limit_l_max 31 _diffrn_reflns_theta_min 1.72 _diffrn_reflns_theta_max 26.37 _reflns_number_total 4335 _reflns_number_gt 3366 _reflns_threshold_expression >2sigma(I) _computing_data_collection 'APEX2 (Bruker, 2004)' _computing_cell_refinement 'SAINT (Bruker, 2004)' _computing_data_reduction 'SAINT (Bruker, 2004)' _computing_structure_solution 'SHELXTL (Bruker, 2004)' _computing_structure_refinement 'SHELXTL (Bruker, 2004)' _computing_molecular_graphics 'SHELXTL (Bruker, 2004)' _computing_publication_material 'SHELXTL (Bruker, 2004)' _refine_special_details ; Refinement of F^2^ against ALL reflections.
