Abstract
A new crystal 2-aminopyridinium para-nitro benzoate (C 5H 7N 2 +·C 7H 4NO 4 −) has been synthesized by the reaction of 2-aminopyridine with para-nitro benzoic acid by slow evaporation method. As synthesized crystals have been characterized by X-ray diffraction (XRD), Fourier transformed infrared (FTIR), and Ultra violet (UV) spectral studies. The XRD and FTIR results indicated that the synthesized compound has the crystal structure of monoclinic with space group P2 1 with lattice parameters a, b, c and β of 7.9403(12) Å, 6.7719(6) Å, 11.1120(15) Å and 99.272(6)° respectively. The synthesized crystal exhibits the UV absorption edge at around 334 nm with the estimated direct band gap ( E g) of 3.53 eV. It is observed from the above studies that the crystal has the maximum transparency in the entire visible region and hence the crystal should exhibit a nonlinear optical property. Further the band gap of the as synthesized crystals was determined to be around 3.53 eV, which makes the crystal suitable for the fabrication of optoelectronic devices. The crystal does not have any inversion symmetry and hence it also exhibits piezoelectricity.
