We have synthesized and evaluated the biological properties of a compound of the type [η6-p-cymene)Ru(EtATSC)Cl]Cl (1) where EtATSC = 2-anthracen-9-ylmethylene-N-ethylhydrazinecarbothioamide, a thiosemicarbazone. The complex has been characterized by elemental analysis, spectroscopically (NMR, UV-Vi...
