The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. ; _refine_diff_density_max 0.256 _refine_diff_density_min -0.159 _refine_diff_density_rms 0.051 _refine_ls_abs_structure_details ; Flack x determined using 714 quotients [(I+)-(I-)]/[(I+)+(I-)] (Parsons, Flack and Wagner, Acta Cryst.
