Weighted R-factors wR and all goodnesses of fit S are based on F^2^. 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. Note the paucity of data which leads to a low quality refinement, manifesting itself as large temperature factors for all atoms and the need for geometrical restraints on the carbons of the vinyl groups. ; _diffrn_orient_matrix_UB_11 0.05929 _diffrn_orient_matrix_UB_12 -0.03523 _diffrn_orient_matrix_UB_13 0.01634 _diffrn_orient_matrix_UB_21 -0.03650 _diffrn_orient_matrix_UB_22 -0.06234 _diffrn_orient_matrix_UB_23 -0.00389 _diffrn_orient_matrix_UB_31 0.02208 _diffrn_orient_matrix_UB_32 -0.00844 _diffrn_orient_matrix_UB_33 -0.03949 #------------------------------------------------------------------------------ loop_ _atom_type_symbol _atom_type_oxidation_number _atom_type_number_in_cell _atom_type_scat_dispersion_real _atom_type_scat_dispersion_imag _atom_type_scat_source Si 0 32 0.082 0.070 'International Tables' O 0 24 0.011 0.006 'International Tables' C 0 128 0.003 0.002 'International Tables' H 0 256 0.000 0.000 'International Tables' #------------------------------------------------------------------------------ loop_ _atom_site_label _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_U_iso_or_equiv _atom_site_occupancy _atom_site_thermal_displace_type _atom_site_calc_flag _atom_site_calc_attached_atom SI(1) 0.6083(9) 0.891(1) 0.9349(6) 0.1443 Uani 1 d .
