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
