1-Alkyl-1-methylpiperazine-1,4-diium Salts: Synthetic, Acid-Base, XRD-analytical, FT-IR, FT-Raman Spectral and Quantum Chemical Study
Original language description
We report the preparation and results of vibrational spectral analysis, which were obtained using both FT-IR and FT-Raman spectroscopy, for three 1-alkyl-1-methylpiperazine-1, 4-diium salts (AMPSs), where alkyl is benzyl 4a, n-octadecyl 4b, and methyl 4c, respectively. These were prepared by multistep synthesis from piperazine. The acid-base study of AMPSs was performed and corresponding acid-base constants were obtained. Single crystals of AMPSs suitable for XRD-analysis were obtained and analyzed. Thecomplete vibrational assignments of wavenumbers were made on the basis of a potential energy distribution. The HOMO and LUMO analysis was used to determine the charge transfer within the molecules. The calculated first hyperpolarizabilities of AMPSs 4a-4c are 48.34, 57.77 and 123.41 times that of urea.
