In this study, we synthesized a hybrid compound, namely 4-carboxyphenylammonium dihydrogen monophosphate (C7H8O2N+.H2PO4−)[4-CADP], and successfully grew single crystals using the slow evaporation technique from an aqueous solution. Impedance measurements were conducted over frequency range spanning 1Hz to 1MHz. Various electrical properties systematically examined analyzed. To best of our knowledge, approach has not been used before for many works carried out by spectroscopy impedance. The...
