Structural and physical characterizations of an organic Dispiro-Oxindolopyrrolidines single crystal for magnetic applications

Abstract An organic dispiro-oxindolopyrrolidine (DOP) crystalline salt was synthesized by reflux method using methanol as a solvent. Molecular structure and lattice parameter of the grown crystalline salt was refined using SHELX program. The 13C NMR and 1H spectral analysis was used to identify the molecular structure. CHN elemental analysis was studied for DOP single crystal. The crystalline perfection of the crystal was studied using high resolution X-ray diffraction analysis. The curves are significantly sharp having a full width at half maximum (FWHM) of 37 arc sec for DOP crystal. The specific heat capacity of the compound was measured and found to be 1.3-2.8 J g/K from room temperature to 90 °. The mechanical properties of the compound was examined using Vicker's hardness tester. The magnetic property of the DOP crystal was studied using VSM analysis.
