explored as ligands. The complexes [PdCl2(L1/L2)] (1/7), [PtCl2(L1/L2)] (2/8), [RuCl(η6-C6H6)(L1/L2)][PF6] (3/9), [RuCl(η6-p-cymene)(L1/L2)][PF6] (4/10), [RuCl(η6-p-cymene)(NH3)2][PF6] (5) and [Ru(η6-p-cymene)(L1)(CH3CN)][PF6]2·CH3CN (6) have been synthesized. The L1–L3 and complexes were found to give characteristic NMR (Proton, Carbon-13 and Se-77). The crystalstructures of complexes 1, 3–6, 9 and 10 have

for the development of RuII arene complexes (arene=p‐cymene or biphenyl) bearing mono‐, bi‐, or tridentate am(m)ine ligands as anticancer agents, a series of ammine, ethylenediamine, and diethylenetriamine complexes were prepared by different synthetic routes. Especially the synthesis of mono‐, di‐, and triammine complexes was found to be highly dependent on the reaction conditions, such as stoichiometry

The [(eta(6)-p-cymene)RuCl(mu-Cl)}(2)] reacts with N-2-(phenylthio) ethyl} morpholine (L) and excess NH4PF6 in CH3OH at room temperature (24 h), resulting in [(eta(6)-p-cymene) RuCl2(L)][PF6] (1) and [(eta(6)-p-cymene) RuCl(NH3)(2)][PF6] (2) unexpectedly. The complex 1 is first example of a 17e(-) half-sandwich complex of eta(6)-arene with Ru(III) formed due to unexpected oxidation of Ru(II) in the presence of excess NH4PF6. The 1 is authenticated by EPR and on the basis of DFT calculations. The single crystal structures authenticate both 1 and 2. The Ru-S bond length in 1 is 2.413(3) angstrom whereas in 2 Ru-N bond distances are 2.141(3) and 2.149(3) angstrom. Attempt to catalyze transfer hydrogenation of ketones with 2-propanol with 1 has given spherical and block shaped Ru-RuS2 (70: 30 w/w%) nano-particles of average size 5-8 nm. (C) 2012 Elsevier B. V.

Attempts to use the same protocol for the synthesis of [(η6-p-cymene)OsII(NH3)2Cl](PF6) led to the isolation of the binuclear triply methoxido-bridged arene-osmium compound [(η6-p-cymene)Os}2(μ-OCH3)3](PF6) (3). Both compounds were characterised by X-ray crystallography and 1H NMR spectroscopy, and the ruthenium complex also by spectroscopic
