“…The signals at 169.85, 179.63, and 182.95 ppm are due to the carbons of COOH/COO of the two maleate anions. The signal at 138.93 ppm is attributed to carbons in the HC=CH group present in the maleate anions[11].…”

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
