Special details top
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
planes. |
Refinement. The structure was solved with SHELX97 by Patterson methods and refined
using SHELX97. Refinement of F2 against ALL reflections. The
weighted R-factor wR and goodness of fit S are based on
F2, conventional R-factors R are based on F,
with F set to zero for negative F2. The threshold expression
of F2 > σ(F2) is used only for calculating
R-factors(gt) etc. and is not relevant to the choice of
reflections for refinement. R-factors based on F2 are
statistically about twice as large as those based on F, and R-
factors based on ALL data will be even larger. |
