Experimental. One distinct cell was identified using SMART (Bruker, 2001). Four frame series were integrated and filtered for statistical outliers using SAINT (Bruker, 2001) then corrected for absorption by integration using SHELXTL/XPREP (Bruker, 2001) before using SAINT/SADABS(Bruker, 2001) to sort, merge, and scale the combined data. A series of identical frames was collected twice during the experiment to monitor decay. No decay correction was applied. |
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. Structure was phased by direct methods. Systematic conditions suggested the un??ambiguous space group. The space group choice was confirmed by successful convergence of the full-matrix least-squares refinement on F2. The highest peaks in the final difference Fourier map were in the vicinity of atoms O1, O2 and AS1; the final map had no other significant features. A final analysis of variance between observed and calculated structure factors showed little dependence on amplitude or resolution. |
