“…At low frequencies, all the mechanisms of polarization contribute to the dielectric constant, and with the increase in frequency, the contributions from different polarizations start decreasing. Similar observations of dielectric behaviors for tartrate and maleate samples were studied [21,22]. From these figures, it is known that the compound 1 has a high dielectric constant compare to the compound 2.…”

Two new 1-benzhydrylpiperazinium carboxylates with tartrate and maleate, (C 17 H 21 N 2 )(C 4 H 5 O 6 ) and (C 17 H 22 N 2 )(C 4 H 3 O 4 ) 2 , have been synthesized and characterized. Crystal structure determinations show that the compounds crystallize in the P2 1 and the P2 1 /c space groups of the monoclinic system, respectively. Only in the maleate the organic group is protonated on both nitrogen atoms of piperazine ring. The infrared spectra of these compounds reported from 400 to 4000 cm -1 confirmed the presence of the principal bands assigned to the internal modes of cations and anions of both compounds. The optical band gaps were calculated and found to be 3.46 and 4.14 eV for tartrate and maleate, respectively. Different molecular motions were determinate via dielectric relaxation spectroscopy. Measurements of AC conductivity as a function of frequency at different temperatures indicated the hopping conduction mechanism. The number of 13 C CP-MAS NMR lines is in good agreement with the crystallographic data. Graphical abstract
