Abstract
Dinuclear arene Ru complexes [(?6-arene)Ru(?-Cl)Cl]2 (arene = C6H6; p-iPrC6H4Me; C6Me6) and monomeric cyclopentadienyl complex [(Cp)Ru(PPh3)2Cl] react with polypyridyl N ligands L1 (3-(pyridin-2-yl)-1H-1,2,4-triazole) and L2 (1,3-bis(di-2-pyridylaminomethyl)benzene) in MeOH to afford cationic mononuclear compds., [(?6-arene)Ru(L1)Cl]+ (arene = C6H6 (1); p-iPrC6H4Me (2); C6Me6 (3)), [(?6-arene)Ru(L2)Cl]+ (arene = C6H6 (4); p-iPrC6H4Me (5); C6Me6 (6)), [(Cp)Ru(L1)(PPh3)]+ (7) and [(Cp)Ru(L2)(PPh3)]+ (8). All cationic mononuclear compds. were isolated as their hexafluorophosphate salts and characterized by elemental analyses, NMR and IR spectroscopic methods and some representative complexes by UV-visible spectroscopy. The solid state structures of two derivs., [6]PF6 and [7]PF6, were detd. by x-ray structure anal. [on SciFinder(R)]
