Polyoxa[n]ruthenocenophanes and 1,n-dioxathia[n]ruthenocenophanes were prepared. The complexes of the ruthenocenophanes with transition metal cations were isolated. The 1H-NMR and electronic spectra of the silver(I) ion-complexed 1,4,7,10,13,16-hexaoxa[16]ruthenocenophane suggested the presence of strong electron-transfer interaction between the complexed silver(I) cation and the ruthenium atom of the ruthenocene nucleus.

A series of ferrocenyl and ruthenocenyl conjugates with colchicine bearing a 1,2,3-triazole moiety were synthesized and their anticancer properties were evaluated. We found that the most potent metallocenyl derivatives Rc4 and Rc5 are 6–7 times more cytotoxic toward HepG2 cells, while Fc4 and Fc5 are two times more cytotoxic toward HCT116 cells as colchicine. We also found that compounds Fc4, Fc5,

A novel 2D triangular brick-wall framework based on CMCR and bpe with included ruthenocene guest molecules is formed with time by conversion of a 1D wave-like polymer structure with an accompanying bowl-to-boat conformational change of the CMCR molecules.

the presence of alkalimetal hydroxides and by the reaction of 1,1′-bis(2-chloroethoxy)ruthenocene with dithiolate in the presence of sodium hydroxide, respectively. The extraction ability of their compounds was excellent for mercury(II) and thallium(I) ions. The ruthenocenophanes with oxygen atoms attached to the ruthenocene nucleus showed excellent extraction ability for a silver(I) ion, although

Efficient Synthesis of Ruthenium(II) η<sup>5</sup>-Dienyl Compounds Starting from Di-μ-chlorodichloro- bis[(1−3η:6−8η)-2,7-dimethyloctadienediyl]diruthenium(IV). Versatile Precursors for Enantioselective Hydrogenation Catalysts
The dimeric complex di-μ-chlorodichloro-bis[(1−3η:6−8η)-2,7-dimethyloctadienediyl]diruthenium(IV) in the presence of base reacts with cyclic and acyclic dienes to the corresponding bis(η5-dienyl)ruthenium(II) compounds. Crystalline yellow compounds have been isolated in high yields for dienyl = cyclopentadienyl, pentamethylpentadienyl, cycloheptadienyl, indenyl, dimethylpentadienyl, and trimethylpentadienyl
