A comparative structural study on sodium and potassium N-chloroarenesulfonamidates was carried out using x-ray diffraction and IR spectroscopy as exptl. techniques. As shown by crystallog. studies, the sodium ions tend to incorporate more water oxygen atoms in their coordination spheres than the potassium ions, while the potassium congeners prefer the interaction with sulfonamidate moieties. The marked dissimilarity between the compositions of the coordination spheres as well as the different tendency of the sodium and potassium salts to absorb moisture from the air were attributed to the different sizes of the sodium and potassium ions. The opposite shifts of the ν as(SO2) and ν(SN) bands upon dehydration were ascribed to an increased polarization of the sulfonyl group by the metal centers. Based on IR spectroscopic observations, a weakening of the N-Cl bonds is suspected in the water-free compounds, which may contribute to the known thermal instability of the dehydrated salts of N-chloroarenesulfonamides. Various sections of IR spectra as well as x-ray powder diffraction patterns proved to be suitable to identify the water-free and hydrated samples.
