Role of Adsorbed H, C, O, and CO on the Atomic Structure of Free and MgO(100)-Supported Ir-4 Clusters: An ab Initio Study

Zeljko Sljivancanin, Alfonso Baldereschi, Vladan Stevanovic

We applied density functional theory based on ultrasoft pseudopotentials to study the structural properties of Ir-4 clusters both in the gas phase and adsorbed on a MgO(100) surface. To resolve the discrepancy between experimental data which suggest a tetr ...

Discovery, structure, and anticancer activity of an iridium complex of diselenobenzoquinone

Paul Joseph Dyson, Anna Katherine Renfrew

Caught in the act: The first stable η4-diseleno-p-benzoquinone complex, [Cp*lr(η4-C6H4Se2)], has been isolated. The X-ray structure confirms the coordination of the elusive diselenobenzoquinone intermediate. The anticancer activity of this complex was comp ...

Anticancer activity of new organo-ruthenium, rhodium and iridium complexes containing the 2-(pyridine-2-yl)thiazole N,N-chelating ligand

Paul Joseph Dyson, Angela Casini, Fabio Edafe

The dinuclear dichloro complexes [(η6-arene)2Ru2(μ-Cl)2Cl2] and [(η5-C5Me5)2M2(μ-Cl)2Cl2] react with 2-(pyridine-2-yl)thiazole (pyTz) to afford the cationic complexes [(η6-arene)Ru(pyTz)Cl]+ (arene = C6H6 (1), p-iPrC6H4Me (2) or C6Me6 (3)) and [(η5-C5Me5)M ...

Next-Generation Anticancer Metallodrugs

Angela Casini

More than 99% of currently approved clinical drugs are organic compounds. In contrast, the percentage of metal-containing drugs (metallodrugs) is very low. In cancer chemotherapy, however, platinum coordination compounds represented by cisplatin and deriva ...

Light-Induced Water Splitting with Hematite: Improved Nanostructure and Iridium Oxide Catalysis

Michael Graetzel, Kevin Sivula, Stanley David Tilley, Maurin Cornuz

Revved-up rust! Light-induced water splitting over iron oxide (hematite) has been achieved by using a particle-assisted deposition technique and IrO2-based surface catalysis. Photocurrents in excess of 3 mA cm-2 were obtained at +1.23 V versus the reversib ...
