Synthesis and physico-chemical properties of a new non-centrosymmetric 2-ammoniumbenzamide trioxonitrate crystals [C7H9N2]NO3

摘要

2-Ammoniumbenzamide trioxonitrate crystals (2-ABN) were prepared and grown at room temperature. This compound crystallizes in the orthorhombic system with non-centrosymmetric space group. The unit cell dimensions are a = 4.8900(9) , , with and . The structure refined to a reliability R factor of 4.34%. The 2-ABN structure consists of 2-ammoniumbenzamide cations and trioxonitrate anions interconnected by hydrogen bonds originating from amine group donors [], so as to build a three-dimensional arrangement. The crystal structure, the thermal behaviour and the IR spectroscopic studies were discussed. The optical studies reveal that the 2-ABN crystal could be a good candidate for nonlinear optical devices. The dielectric properties, real and imaginary dielectric permittivities ( and ) and dielectric loss tangent (tan ()), of the crystal at different frequencies of the applied field are reported.
