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...
متن کاملPhysicochemical 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...
متن کاملTetraethylammonium trichlorido(η6-p-cymene)ruthenate(II)
In the title salt, [(C(2)H(5))(4)N][RuCl(3)(C(10)H(14))], the Ru(II) atom shows an octa-hedral coordination in which the aromatic ring of the p-cymene mol-ecule occupies three coordination positions.
متن کاملDichlorido(η6-p-cymene)(ethoxydiphenylphosphane)ruthenium(II)
The title compound, [RuCl2(C10H14)(C14H15OP)], is an Ru(II) complex in which an η(6)-p-cymene ligand, two chloride anions and the P atom of an ethoxydiphenylphosphane ligand form a piano-stool coordination environment about the central Ru(II) atom.
متن کامل(η6-p-Cymene)bis(trichloridostannyl)(triethoxyphosphine-κP)ruthenium(II)
In the title complex, [RuSn(2)(C(10)H(14))Cl(6)(C(6)H(15)O(3)P)], the Ru-Sn bond lengths [2.5619 (3) and 2.5669 (3) Å] are about 0.3 Å shorter than the sum of the covalent Ru and Sn radii (1.46 + 1.39 = 2.85 Å), in line with other structurally characterized arene ruthenium trichlorido-stannyl derivatives. The Ru(II) atom is surrounded by a para-cymene, a triethylphosphite and two trichloridosta...
