NCN pincer ligands based on 1,2,4-triazole and their corresponding palladium(II) complexes have been synthesized by the reaction of 1,3-bis(1H-1,2,4-triazol-1-ylmethyl)benzene derivatives with palladium(II) acetate. All compounds are ortho,ortho-metalated. Chiral complexes were obtained by using pincer ligands with substituents on the arms. The chiral complexes are conformationally rigid up to 150 °C.
