All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. 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.   Refinement. Refinement of *F*^0^ against ALL reflections. The weighted *R*-factor *wR* and goodness of fit *S* are based on *F*^0^, conventional *R*-factors *R* are based on *F*, with *F* set to zero for negative *F*^0^. The threshold expression of *F*^0^ \>
