“…3b. The two broad resonances located at 44.95 and 50.67 ppm are assigned to the piperazine ring carbon atoms [10]. This is in agreement with only one organic cation being present in the asymmetric unit ''cell'' as revealed by X-ray structure determination.…”

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

Optically transparent formic acid (FA) doped potassium dihydrogen phosphate (KDP) crystal of dimension 21×15×9 mm3 has been grown by slow evaporation solution technique (SEST). The X‐ray diffraction (XRD) technique was used to confirm the cell parameters and the shifts in peak positions of identified reflecting planes. The incorporation of FA in KDP has been qualitatively analyzed by fourier transform infrared analysis. The UV‐visible absorption spectrum of crystals has been recorded in the range of 200 to 900 nm and the doped KDP crystal is found to have improved optical parameters than pure KDP. The color centered photoluminescence emission spectrum of grown crystal has been illustrated in visible region. The mechanical behavior of pure and doped KDP crystal has been investigated using the Vicker's microhardness analyzer and hardness parameters have been calculated. The effect of FA on thermal stability of KDP crystal was examined by means of thermogravimetric and differential thermal analysis. The temperature dependent dielectric behavior of crystals was studied.

“…Table 2 summarizes the experimental details and the results of the Z-Scan technique for PzA. The calculated values of nonlinear refractive index, nonlinear absorption coefficient and third order NLO susceptibility are found to be slightly high with respect to piperazinium meso tartrate [14], piperazinium 4-nitrophenolate monohydrate [15] and adipate crystals [18,19]. The hydrogen bond interactions between the piperazinium cations and the long adipate anions can be attributed to such high NLO responses.…”
