Fingerprint Intermolecular Interactions of Sodium and Potassium Complexes

The complex of sodium and potassium salts is characterized by using UV-Visible, FT-IR, NMR, Singlecrystal X-ray diffraction, Hirshfeld surfaces, and Fingerprint plots. The crystal belongs to the monoclinic system and p121/n1, p21/n space group. The corresponding peaks for chlorine atoms are absent in the NMR spectra of the complexes. The small red spot in Hirshfeld surfaces indicates the presence of CH...π interactions in the sodium complex. Absence of Metal...Metal interactions were also observed in both sodium and potassium complex. Fingerprint plots of Hirshfeld surfaces were used to detect and examine the percentage of hydrogenbonding interactions.
