Abstract

A new organic-organic salt, bis (4-nitrophenol) 2, 4, 6 -triamino 1, 3, 5- triazine monohydrate (BNPM) has been synthesized by slow evaporation technique at room temperature. X-ray powder diffraction studies confirm the crystalline nature of the grown crystals. The UV-Vis spectrum of BNPM shows less optical absorption in the entire visible region. Mechanical strength and its related parameters of BNPM have been determined by Vickers micro hardness test. The dielectric response of BNPM was studied in the frequency range 50Hz to 5 MHz at different temperatures and the results are discussed. DSC measurements on powder sample indicate the phase transition point at 366 and 306 K for heating and cooling respectively. No detectable signal was observed during powder test for second harmonic generation..
