The s.u.'s on the cell parameters are unexpectedly large:
_cell_length_a                    16.531(17)
_cell_length_b                    7.975(8)
_cell_length_c                    13.047(13)
See also the C-alerts?
Do you have any reason for this? Please send me the original printout of the unit cell refinement (Saint-plus)

PLAT961_ALERT_5_G Dataset Contains no Negative Intensities .......          !
PLAT906_ALERT_3_C Large K value in the Analysis of Variance ......      2.350
Generally, both positive and slightly negative intensities are expected
in a data set. Resetting negative intensities to zero may bias the
refinement results and the 'analysis-of-variance' as reported e.g. in
the SHELXL output listing.
Please check in your original dataset if there were no negative intensities.
