Ruthenium Styryl Complexes with Ligands Derived from 2-Hydroxy- and 2-Mercaptopyridine and 2-Hydroxy- and 2-Mercaptoquinoline

Popis výsledku v původním jazyce

A series of ruthenium styryl complexes with potentially noninnocent kappa(2)[N,O](-) or kappa(2)[N,S](-) ligands have been prepared by treatment of 5-coordinated 16-valence-electron ruthenium styryl complexes Ru(CO)Cl(PiPr(3))(2)(CH=CH-C6H4-4R) with deprotonated bidentate 2-hydroxy- or 2-mercaptopyridines or 2-hydroxy- or 2-mercaptoquinolines. These 6-coordinated complexes have been characterized by NMR and IR spectroscopy and by cyclic voltammetry. Moreover, the structures of complexes 1d, 2a, 3c, 5b,and 6b have been established by X-ray crystallography. Our results indicate that the pyridine-derived complexes exist as two isomers that differ with respect to the orientation of the kappa(2)[N,O](-) or kappa(2)[N,S](-) donor ligands relative to the COand alkenyl ligands in the equatorial plane. The equilibrium between the two isomers is thermodynamically controlled. Thus, the relative amount of the minor isomer increases at higher temperatures. With the 2-hydroxyquinoline- or 2-mercap
