functions, and its Pd(II) and Rh(I) complexes were prepared. Ptu behaves as a bidentate ligand forming seven-membered chelation rings in a boat-like conformation. In the case of palladium, this was ascertained by the X-ray determination of the structure of the complexes [Pd(Ptu)2]Cl2·6CHCl3 (1), [Pd(Ptu)2Cl]Cl·EtOH (2) and [Pd(Ptu)2][CoCl4].CHCl3·2EtOH (3). In complexes 1 and 3, the two ligands are related

whereas for silver complexes the coordination of the ligand as P^S chelate is found. The thiourea ligands and their complexes were explored against different cancer cell lines (HeLa, A549, and Jurkat). The thiourea ligands do not exhibit relevant cytotoxicity in the tested cell lines and the coordination of a metal triggers excellent cytotoxic values in all cases. In general, data showed that gold complexes
