Single crystals of N-Acetyl Glycine Phosphite (AGPI) were grown fromaqueous solution by low temperature solution growth technique. Formation of the new crystal has been confirmed by single crystal XRD studies. AGPI belongs to monoclinic system with cell parameters a = 7.419 Å, b = 8.487 Å, c = 9.791 Å. Crystalline quality was found using rocking curve. The presence of functional groups were estimated qualitatively by FTIR analysis. The dielectric studies were carried out to identify the phase transition temperature and to find the dielectric constant. Hysteresis studies were carried out to identify the ferroelectric nature of the material. AFM studies were carried out to understand the ferroelectric surface and the domain structure. © Taylor & Francis Group, LLC.
