Abstract
Palladium(II) complex [Pd(HL)Cl] (1) (H2L = 2-PhS(C6H4)NH-NC-(COCH3)-NHC6H5) has been synthesized by reacting K2PdCl4 with H2L. The pincer H2L ligand is coordinated to a Pd(II) in an anionic 5 pi electron form via k(3)-SNN to produce neutral 1-trans and 1-cis isomers in the solid state. The structures of two isomers (1-trans and 1-cis) were determined by single crystal X-ray diffraction. Furthermore, complex 1 has been characterized by electrochemical and spectroscopic techniques. Antiproliferative activity was conducted agaisnt two breast cancer cell lines using MIT assay. The complex showed significant antiprliferative activity against breast cancer cell lines and low toxicity toward normal cells. Theoretical calculation was used to predict the electronic transition of the complex 1. (C) 2019 Elsevier B.V. All rights reserved.
