Experimental and Quantum Mechanical Investigation on Two N-Heterocyclic Carbene Palladium Complexes

Abstract

Two palladium complexes bearing different ligands such as N-heterocyclic carbene (NHC), pyridine and phosphines were synthesized and characterized by FT-IR spectroscopy, X-ray crystallography and quantum-chemical computations. DFT calculations have been performed at HSEh1PBE/SDD level of theory. Intermolecular interactions have been studied through two-dimensional fingerprint plots based on Hirshfeld surface analysis. Structural parameters and spectroscopic properties of the complexes are well interpreted by DFT and TD-DFT calculations.
