| Abstract: | A series of di‐nuclear ruthenium arene complexes with TSC ligands ((η6‐p‐cymene)Ru(N1,S‐TSC)]2Cl2, A‐type, 1 and 2 ) and their corresponding analogues ((η6‐p‐cymene)Ru(N2,S‐TSC)]2Cl2, B‐type, 3 and 4 ), in which TSCs act as different coordination mode, have been synthesized and structurally characterized by a variety of physical methods. The molecular structures of 1 , 3 and 4 were determined using single‐crystal X‐ray diffraction analysis. The Gibbs free energy of the two examples of the two types of complexes ( 1 and 3 ) and bonding order in their single‐crystals were discussed using density functional theory (DFT) calculations. The compounds were further evaluated for their in vitro antiproliferative activities against several cancerous and HEK‐293 T noncancerous cell lines, and the results indicate that B‐type complexes show stronger cytotoxicity than A‐type complexes. Furthermore, the interactions of the compounds with DNA were investigated by electrophoretic mobility spectrometry studies. |
