Cationic trigonal bipyramidal complexes of the type [PtRL(NN′)(olefin)]BF4 with various hydrocarbyl (R), neutral monodentate (L), and bidentate nitrogen (NN′) ligands have been prepared and characterized by elemental analysis, conductivity measurements, and 1H NMR spectroscopy. The coordination around PtII is trigonal bipyramidal, with the olefin and the NN′ ligand in equatorial positions. The reversible

This article describes the synthesis and characterization of novel cationic five-coordinate Pt(II) complexes containing nitrogen sugar-based ligands. The cytotoxicity of the complexes was evaluated on different cell lines with the expectation that both the coordinative saturation and the sugar moiety cooperate to enhance their biologicalactivity. In fact, the complexes resulted to be more active than

New five-coordinate Pt(II) complexes containing a glycosylated carbene fragment were synthesized. A member of this class shows very high in vitro cytotoxicity and an exceptional selectivity toward malignant cells. The complex lacking the sugary portion fails in the recognition of cancer cells. The results support the use of glycosylation in the design of carbene Pt-based anticancer agents.

Abstract The synthesis and characterization of five-coordinateplatinum(II) complexes of general formula [PtClX(NN)(uns)] (X=Cl, Me; NN=bidentate nitrogen ligands; uns=substituted alkene containing carboxy or amino groups) are described. In some cases, the hindered rotation of the prochiral unsaturated ligand around the Pt-alkene bond, alone or in conjunction with a ligand environment affording a
