PROBLEM: _refine_ls_goodness_of_fit_all is missing (this is chi, i.e.
RESPONSE: We did not report any GOF, as its definition is not suitable for up-to-date detectors. Modern point sensitive Mythen detectors (the devices we used) provide large global and local count rates, smooth intensity distribution with little statistical fluctuations and a high dynamic range; therefor weak reflections can be accurately measure in proximity of strong peaks. In addition these devices are almost noise free. Accordingly the powder pattern is treated by the software like if the scan time was far too long, although the applied scan time was moderate (see Table S1 in the supporting information). This leads to an artificial high GOF value, even for good fits. Hence we reported Rwp-, are R-F^2^- and R-p-values as well as a figure (Table S1) showing the fit of the whole powder pattern as the quality of the refinement might be better judged be these criteria. This problem is well known to powder diffractionists using a synchrotron beam line source and a 2D image plate detector or an array of Mythen detectors.

PROBLEM: Calculated and Reported Mol. Weight Differ by ..      48.33 Check
RESPONSE: According to the limits of the XRPD method we did not do any attempt to determine and refine the hydrogen positions. Accordingly hydrogens were not included into the cif files. Accordingly hydrogen atoms that are apparent in the solid phase are not included into the cif-file. That is why there is a difference between the reported and calculated molar mass (PLAT043 ALERT 1 B).

PROBLEM: Isolated Oxygen Atom (H-atoms Missing ?) .......         O4 Check
RESPONSE: The sites O(4), O(5), O(6), O(7) represent non-coordinated hydrate water. According to the limits of the XRPD method we did not do any attempt to determine and refine the hydrogen positions of these water molecules.

PROBLEM: Low Bond Precision on  C-C Bonds ...............     0.0375 Ang.
RESPONSE: Due to the vast peak overlap at high diffraction angle, data were only collected and used up to a diffraction angle of 100.0\%2 \q (Supporting Information, Figure S1). Accordingly the precision of the C-C bond is low. This is why the C-C bond of the acetate ion was refined within the rigid body while using restraints (see Structure Determination Section in the manuscript).
