;Barry, Nicolas P.E. ;Govindaswamy, Padavattan ;Furrer, Julien; Self-assembly of 5,10,15,20-tetra(4-pyridyl)porphyrin (tpp-H2) tetradentate panels with dinuclear arene ruthenium clips [Ru2 (η6-arene)2 (dhbq)Cl2] (arene = C6H5Me, p-PriC6H4Me, C6Me6; dhbq = 2,5-dihydroxy-1,4-benzoquinonato) affords the cationic organometallic boxes [Ru8 (η6-C6H5Me)8 (tpp-H2)2 (dhbq)4]8+ ([1]8+), [Ru8 (η6-p-PriC6H4Me)8 (tpp-H2)2(dhbq)4]8+ ([2]8+) and [Ru8 (η6-C6Me6)8 (tpp-H2)2 (dhbq)4]8+ ([3]8+). These octanuclear cations have been isolated as their triflate salts and characterised by mass spectrometry, NMR and IR spectroscopy. The molecular structure of these systems was deduced by one-dimensional and two-dimensional NMR experiments (ROESY, COSY, HSQC). - PublicationAccès libreMono and dinuclear arene ruthenium complexes containing 6,7-dimethyl-2,3-di(pyridine-2-yl)quinoxaline as chelating ligand: Synthesis and molecular structure(2007)
; ; ;Govindaswamy, PadavattanSaïd-Mohamed, CynthiaThe mononuclear cations of the general formula [(η6-arene)RuCl(dpqMe2)]+ (dpqMe2 = 6,7-dimethyl-2,3-di(pyridine-2-yl)quinoxaline; arene = C6H6, 1; C6H5Me, 2; p-PriC6H4Me, 3; C6Me6, 4) as well as the dinuclear dications [(η6-arene) 2Ru2Cl2(μ-dpqMe2)]2+ (arene = C6H6, 5; C6H5Me, 6; p-PriC6H4Me, 7; C6Me6, 8) have been synthesised from 6,7-dimethyl-2,3-di(pyridine-2-yl)quinoxaline (dpqMe2) and the corresponding chloro complexes [(η6-C6H6)Ru(μ-Cl)Cl]2, [(η6-C6H5Me)Ru(μ-Cl)Cl]2, [(η6-p-PriC6H4Me)Ru(μ-Cl)Cl]2 and [(η6-C6Me6)Ru(μ-Cl)Cl]2, respectively. The X-ray crystal structure analyses of [1][PF6], [3][PF6] and [6][PF6]2 reveal a typical piano-stool geometry around the metal centre; in the dinuclear complexes the two chloro ligands, with respect to each other, are found to be trans oriented.
