Arene ruthenium complexes as anticancer agents

Süss-Fink, Georg

In: Dalton Transactions, 2010, vol. 39, no. 7, p. 1673-1688

Neutral or cationic arene ruthenium complexes providing both hydrophilic as well as hydrophobic properties due to the robustness of the ruthenium–arene unit hold a high potential for the development of metal-based anticancer drugs. Mononuclear arene ruthenium complexes containing P- or N-donor ligands or N,N-, N,O- or O,O-chelating ligands, dinuclear arene...

2,3,4,7-Tetrahydro-1H-inden-2-ol: synthesis, molecular structure and coordination chemistry

Vieille-Petit, Ludovic ; Therrien, Bruno ; Süss-Fink, Georg

In: Polyhedron, 2004, vol. 23, no. 4, p. 687-691

2,3,4,7-Tetrahydro-1H-inden-2-ol (1) has been synthesised by Birch reduction of indan-2-ol. A single-crystal X-ray structure analysis of 1 shows the compound to exist as hydrogen-bonded polymers along the c-axis due to the presence of a series of hydrogen-bonds between hydroxo functions. The ferrocene ester derivatives, ferrocene carboxylic acid...
