Ruthenium piano-stool complexes bearing imidazole-based PN ligands [PDF]

Journal of Organometallic Chemistry, 2012
A variety of piano-stool complexes of cyclopentadienyl ruthenium(II) with imidazole-based PN ligands have been synthesized starting from the precursor complexes CpRu(C10H8)]PF6, CpRu(NCMe)(3)]PF6 and CpRu(PPh3)(2)Cl]. PN ligands used are imidazol-2-yl, -4-yl and -5-yl phosphines.

DNA Noncovalent Interactions of Dinuclear η⁶-Arene Ru(II) Complexes: Influence of Complex Charge and Bridging Ligand Length on DNA Binding Mode and Cytotoxic Activity. [PDF]

Chemistry
A library of cationic dinuclear Ru(II)‐η⁶‐arene analogues was developed to assess how overall charge and Ru–Ru distance influence DNA binding noncovalent interactions and cytotoxicity. NMR studies showed multiple binding modes with the B‐form DNA oligonucleotide d(5΄‐CGCGAATTCGCG‐3΄)2, while the complexes displayed micromolar IC50 values against MCF‐7,

Exploring Rhenium Arene Piano-Stool Chemistry with [Re(η6-C6H6)(NCCH3)3]+: A Powerful Semi-Solvated Precursor

Inorganic Chemistry, 2023
Thermal treatment of the ReIII hydride complex [ReH(η5-C6H7)(η6-C6H6)]+ in CH3CN results in the formation of [Re(η6-C6H6)(NCCH3)3]+. This semi-solvated complex is remarkably stable under an ambient atmosphere and exhibits a fast CH3CN self-exchange ...

Dichlorido(η6-p-cymene)(ethoxydiphenylphosphane)ruthenium(II)

Acta Crystallographica Section E, 2012
The title compound, [RuCl2(C10H14)(C14H15OP)], is an RuII complex in which an η6-p-cymene ligand, two chloride anions and the P atom of an ethoxydiphenylphosphane ligand form a piano-stool coordination environment about the central RuII atom.
