A New Palladium(II) Complex With 3-Picoline and Diclofenac: Synthesis, Crystal, Spectroscopic, Thermal and DFT Studies

Abstract

A novel palladium(II) complex with 3-picoline and diclofenac ligands was synthesized using [PdCl2(3-pic)2] as the precursor. The synthesized complex is characterized by elemental and thermal and spectroscopic methods. Single X-Ray analysis confirms that the complex has square plane geometry and the compound of formula is [Pd(dicl)2(3-pic)2]. Electronic properties of the complex have been probed by natural bond orbital (NBO) population analyses. Furthermore, relative stabilities of the complexes have been also compared in theoretical insight based on DFT computations since complex [PdCl2(3-pic)2] is the precursor of [Pd(dicl)2(3-pic)2]. Thermal analysis shows that the complex is stable up to 200 oC.
