Abstract
The title compound of phenyl-thiocarbamic acid-O-pyridin-4-ylmethyl ester has been synthesized and characterized by elemental analysis, IR, electronic spectroscopy and X-ray single crystal diffraction. Density functional theory (DFT) method calculations of the structure, atomic charge distributions and the thermodynamic properties at different temperatures have been performed. Calculated results show that DFT method at B3LYP/6-311G** level can well reproduce the structure of the title compound. The predicted vibrational frequencies are compared with the experimental ones and they support each other on the whole. The atoms of sulfur, oxygen and the atom of nitrogen from pyridine ring all have bigger negative charges, which make the title compound become a multidentate organic ligand. The correlation equations of the thermodynamic properties of $$C_{p,m}^\circ$$ and $$S_{m}^\circ$$ with temperature are also obtained.
