Popis: A series of ligands containing pyrenyl core which are PyEt1, PyEt2, and PyEt3 have been successfully synthesized. PyEt2, a bidentate ligand and PyEt3, a tridentate ligand were used to prepared Pd(II) complexes by reactions with PdCl2(CH3CN)2. The titled compounds displayed intriguing geometries around the central palladium atoms. 1H-NMR results showed that palladium in Pd-PyEt3 adopts a five-coordinate configuration. Keywords: Pyrene, palladium, five coordination. References: [1] M. Zhao, X. Zhou, J. Tang, Z. Deng, X. Xu, Z. Chen, X. Li, L. Yang, L.-J.
