Overview

Piperazinium bis (trifluoroacetate) organic single crystal has been grown by solution growth method for the first-time reported in the literature. Transparent piperazinium bis (trifluoroacetate) single crystal with dimension of 11 mm × 9 mm × 5 mm was collected after a 20 days growth period. The new crystal structural parameters (unit cell & space group) were ensured by single crystal XRD. The crystalline perfection of PTFA crystal was characterized using powder XRD, UV–Visible-NIR, FTIR, TG–DTA, chemical etching, dielectric, Vickers microhardness, and Z -scan analysis. The chemical etching study investigation has shown that the PTFA crystal has less defects. The electrical properties of PTFA crystal have a low density of defects and a low value of dielectric loss found from the dielectric studies. Intermolecular interaction of PTFA is identified by the Hirshfeld surface analysis. The third harmonic generation study was carried out to investigate centrosymmetric nature of PTFA crystal. In order to find out the nonlinear susceptibility ( χ (3) ), Z -scan analysis was used.
