α-Diimines as Versatile, Derivatizable Ligands in Ruthenium(II)p-Cymene Anticancer Complexes

Helicates as Versatile Supramolecular Complexes.

Physicochemical Studies and Anticancer Potency of Ruthenium η6-p-Cymene Complexes Containing Antibacterial Quinolones

With the aim of exploring the anticancer properties of organometallic compounds with bioactive ligands, Ru(arene) compounds of the antibacterial quinolones nalidixic acid (2) and cinoxacin (3) were synthesized, and their physicochemical properties were compared to those of chlorido(η(6)-p-cymene)(ofloxacinato-κ(2)O,O)ruthenium(II) (1). All compounds undergo a rapid ligand exchange reaction from...

Solution Equilibrium Studies of Anticancer Ruthenium(II)--p-cymene Complexes of Pyridinecarboxylic Acids

Stoichiometry and stability of antitumor ruthenium(II)-η-p-cymene complexes of picolinic acid and its 6-methyl and 6-carboxylic acid derivatives were determined by pHpotentiometry, H NMR spectroscopy and UV/Vis spectrophotometry in aqueous solution in the presence or absence of coordinating chloride ions. The picolinates form exclusively monoligand complexes in which they can coordinate via the...

Ferrocenylalkynes as ligands in transition metal complexes

Several ferrocenylalkynes have been prepared and their reaction with dicobalt octacarbonyl led to the formation of [Co2(CO)6(μ-η 2 : η-ethynylferrocene)] 1, [Co2(CO)6(μ-η 2 : η-1,4-bis(ferrocenyl)butadiyne)] 2, [(Co2(CO)6)2(μ-η : η,μ-η : η-1,4-bis(ferrocenyl)butadiyne)] 3, [Co2(CO)6(μ-η 2 : η-1-ferrocenylethynyl-2-hydro-1,2-dihydro[60]fullerene)] 4, [Co2(CO)6(μ-η 2 : η-1,1’-bis(phenylethynyl)fe...

Luminescent Iridium(III) Complexes Supported by N-Heterocyclic Carbene-based C^C^C-Pincer Ligands and Aromatic Diimines

Iridium(III) hydrido complexes containing N-heterocyclic carbene (NHC)-based pincer ligand 1,3-bis(1-butylimidazolin-2-ylidene)phenyl anion (C(1)^C^C(1)) or 1,3-bis(3-butylbenzimidazolin-2-ylidene)phenyl anion (C(2)^C^C(2)) and aromatic diimine (2,2'-bipyridine (bpy), 1,10-phenanthroline (phen), 4,4'-dimethyl-2,2'-bipyridine (Me2bpy), or dipyrido-[3,2-f:2',3'-h]-quinoxaline (dpq)) in the form o...
