摘要

In this research, template synthesis and crystal structure of a new HgLI2 complex are presented (L = N-1(4-nitrobenzylidene)-N-2-(2-((E)-(4-nitrobenzylidene)amino)ethyljethane-1,2-diamine). The mercury complex crystallizes in the triclinic system with space group of P (1) over bar. The crystal structure of the complex shows a distorted trigonal bipyramidal geometry around the mercury(II) center; including two land an N atoms of Schiff base ligand in equatorial plane and two iminic N atoms in axial positions. Two five membered mercury containing rings [Hg(-N-C-C-N)] are found in the structure. Some C-H center dot center dot center dot O, N center dot center dot center dot O and pi center dot center dot center dot pi intermolecular interactions causes a supra-molecular network in the solid-state. In addition to crystal structure analysis, density functional theory (DFT) study at the B3LYP/LanL2DZ level of theory has been also performed on the structure. Thereafter some theoretical structural and spectral data were compared with experimental results. Furthermore, total energy levels of HOMO and LUMO orbitals, molecular electrostatic potential, Mullikan atomic charges, thermodynamic and polarizability properties of the complex were calculated. Finally the mercury complex was prepared in nano-structure size confirmed by SEM and XRD analyses. The particles size of the titled complex was evaluated under 40 nm based on Sherrer's formula.
