Uij components of ADPs for disordered atoms closer to each other than 2.0 Angstrom were restrained to be similar. Subject to these conditions the occupancy ratio refined to ??? to ???. Water H atom positions were refined and O-H and H...H distances were restrained to 0.84(2) and 1.36(2) Angstrom, respectively. Some water H atom positions were further restrained based on hydrogen bonding considerations. Water H atom positions were initially refined and O-H and H...H distances were restrained to 0.84(2) and 1.36(2) Angstrom, respectively, while a damping factor was applied. Some water H atom positions were further restrained based on hydrogen bonding considerations. In the final refinement cycles the H atoms were constrained to ride on their carrying oxygen atom (AFIX 3) and the damping factor was removed. ; # Twinned Crystals: _exptl_absorpt_correction_type 'multi-scan' _exptl_absorpt_correction_T_min ? _exptl_absorpt_correction_T_max ? _exptl_absorpt_process_details ; TWINABS 2012/1: Krause, L., Herbst-Irmer, R., Sheldrick G.M. & Stalke D. (2015). J. Appl. Cryst. 48 3-10. ; _refine_special_details ; The crystal under investigation was found to be non-merohedrally twinned. The orientation matrices for the two components were identified using the program Cell_Now, with the two components being related by a 180 degree rotation around the real/reciprocal axis XX. The two components were integrated using Saint and corrected for absorption using twinabs, resulting in the following statistics: The exact twin matrix identified by the integration program was found to be: The structure was solved using dual methods with only the non-overlapping reflections of component 1. The structure was refined using the hklf 5 routine with all reflections of component 1 (including the overlapping ones), resulting in a BASF value of ????. The Rint value given is for all reflections and is based on agreement between observed single and composite intensities and those calculated from refined unique intensities and twin fractions (TWINABS (Sheldrick, 2012)). The data were corrected for absorption using twinabs, and the structure was solved using direct methods with only the non-overlapping reflections of component 1. The structure was refined using the hklf 5 routine with all reflections of component 1 (including the overlapping ones) with a resolution better than 0.75 Angstrom, resulting in a BASF value of ???. The total number of reflections given (_diffrn_reflns_number) is before the cutoff at 0.75 Angstrom. The Rint value (_diffrn_reflns_av_R_equivalents) given is for these reflections and is based on agreement between observed single and composite intensities and those calculated from refined unique intensities and twin fractions before the cutoff at 0.75 Angstrom (TWINABS (Sheldrick, 2012)). Integration proofed problematic due to excessive multiple overlap of reflections, resulting in large numbers of rejected reflections. Attempts were made to adjust integration parameters to avoid excessive rejections (through adjustments to integration queue size, integration box slicing and twin overlap parameters, and omission of box size optimization), which led to less but still substantial numbers of rejected reflections, or to complete but severely deteriorated data (no box size optimization). With no acceptable quality complete data set obtainable through simultaneous integration of both twin domains, the data were instead handled as if not twinned, with only the major domain integrated, and converted into an hklf 5 type format hkl file after integration using the "Make HKLF5 File" routine as implemented in WinGX. The twin law matrix was used as obtained from SAINT, see above. The Overlap R1 and R2 values used were ???, i.e. reflections with a discriminator function less or equal to overlap radius of ??? were counted overlapped, all others as single. The discriminator function used was the "delta function on index non-integrality". No reflections were omitted. The structure was solved using dual methods with the hklf 4 type file and was refined using the hklf 5 type file, resulting in a BASF value of ???. A refinement using the incomplete data obtained through SAINT and TWINABS gave similar refinement statistics, but with higher overall R values (around ???% for R1) and with less well defined ADPs (two atoms NPD or close to NPD). No Rint value is obtainable for the hklf 5 type file using the WinGX routine. The value from TWINABS is given instead, which is for all reflections available and is based on agreement between observed single and composite intensities and those calculated from refined unique intensities and twin fractions (TWINABS (Sheldrick, 2009)).

J. Appl. Cryst. 2002. 35, 168-174. ; # Squeeze: _refine_special_details ; The structure contains additional ??? Ang3 of solvent accessible voids. No substantial electron density peaks were found in the solvent accessible voids (less than ?? electron per cubic Angstrom) and the residual electron density peaks are not arranged in an interpretable pattern. The structure factors were instead augmented via reverse Fourier transform methods using the SQUEEZE routine (P. van der Sluis & A.L. Spek (1990). Acta Cryst. A46, 194-201) as implemented in the program Platon. The resultant FAB file containing the structure factor contribution from the electron content of the void space was used in together with the original hkl file in the further refinement. (The FAB file with details of the Squeeze results is appended to this cif file). The Squeeze procedure corrected for ?? electrons within the solvent accessible voids. ; # Combination of twinning and Squeeze: _refine_special_details ; In addition to the twinning, the structure also exhibits large volume sections consisting of highly disordered solvate or other small molecules. No satisfactory model for the solvate molecules could be developed, and the contribution of the solvate molecules was instead taken into account by reverse Fourier transform methods. The data were first detwinned (using the LIST 8 function of Shelxl2019) and then the cif and fcf files were subjected to the SQUEEZE routine as implemented in the program Platon. The resultant files were used in the further refinement. (Both the hklf 5 type HKL file and the detwinned FAB file are appended to this cif file). A volume of ??? cubic Angstrom per unit cell containing ??? electrons was corrected for. ;
