Refinement. Refinement. For this compound, 9444 numbers of reflections were collected and measured during the refinement. Symmetry related reflections were measured more than once and after merging the symmetry equivalent reflections there were only 3214 reflection left. 12 more reflections were filtered, as σ cutoff was set as 3 and (sin?/x)set to>0.01 (to eliminate reflection measured near the vicinity of beam stop) therefore numbers of reflection reduced to 3202.
