Abstract

New benzhydryl-5,6-dimethyl-(3-methylbenzyl)benzimidazolium salt as N-heterocyclic carbene precursors and their related new Pd-NHC complex PEPPSI-type with the general formula [PdBr2(NHC)(pyridine)] were prepared and theoretically studied. Quantum chemistry computations at the B3LYP/6-311G(d,p)/LANL2DZ level were used to examine the molecular structure, electronic characteristics, and chemical reactivity of the ligand and its Pd complex. Further, the structural characterization of the complex (c) was determined by a single-crystal X-ray diffraction study, which supports the proposed structures and offered a more detailed structural characterization. In addition, their biological activity against.
