Abstract
Thiosemicarbazide zinc(II) picrate (TSCZP) was synthesized and its solubility in the dimethyl sulfoxide and dimethyl formamide solvents was estimated. 0.01g of TSCZP was dissolved in 100cc of dimethyl sulfoxide and dimethyl formamide separately and the conductivity of the solution was measured using conductivity meter. Three dimensional crystal structure of the grown crystal was determined by single crystal X-ray diffraction study. The TSCZP crystallizes in the triclinic system with space group P-1. The presence of the functional groups were confirmed from the Fourier Transform Infrared spectral studies. UV-vis-NIR spectral studies show that the transmittance between 385 and 1100 nm is about 60%. Thermogravimetric and differential thermal analyses reveal the thermal stability of the crystal. The microhardness test was carried out, and the load hardness parameter was measured.
