Abstract
A novel compound of zinc (II) ion, [ZnCl 2 (peta) 2 ] [peta: 4-Pyridinethioamide] was synthesized and characterized by XRD and FT-IR spectroscopy. The geometry around the Zn (II) center can be described as distorted tetrahedron. The crystal packing was stabilized by N–H∙∙∙Cl, N–H∙∙∙S and C–H∙∙∙S intermolecular hydrogen bonds. Molecular modeling of the Zn(II) complex was done by using the Hartree-Fock (HF) and Density Functional Theory (DFT) with 6-311++G (d, p) basis set. The calculated vibrational frequencies were compared with the corresponding experimental data. The time dependent DFT (TD-DFT) method by applying the integral equation formalism-polarized continuum model (IEF-PCM) was performed to investigate the electronic transitions in water and DMSO solvent.
