; ; - PublicationAccès libreOrganometallic boxes built from 5,10,15,20-tetra(4-pyridyl)porphyrin panels and hydroxyquinonato-bridged diruthenium clips(2008)
; 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 libreSelf-assembled chloro-bridged metallo-prismatic cations of the general formula [M6 (η5-C5Me5)6 (μ3-tpt)2 (μ-Cl)6]6+ (M = Rh, Ir; tpt = 2,4,6-tri(pyridin-4-yl)-1,3,5-triazine)(2007)
; Two cationic pentamethylcyclopentadienyl metal-based hexanuclear complexes with trigonal prismatic architecture have been synthesised through a two-step strategy. The dinuclear complexes [M(η5- C5Me5)(μ-Cl)Cl]2 (M = rhodium and iridium) react with 2,4,6-tri(pyridin-4-yl)-1,3,5-triazine (tpt) in dichloromethane to give the trinuclear complexes [Rh3 (η5-C5Me5)3 (μ3-tpt)Cl6] (1) and [Ir3(η5-C5Me5)3 (μ3-tpt)Cl6] (2), respectively. Addition of silver triflate to 1 and 2 in dichloromethane connects two identical triangular panels to form the hexanuclear metallo-prismatic cations [Rh6 (η5-C5Me5)6 (μ3-tpt)2 (μ-Cl)6]6+ (3) and [Ir6 (η5-C5Me5)6 (μ3-tpt)2 (μ-Cl)6]6+ (4), respectively. Cations 3 and 4 have been isolated as their triflate salts and characterised by 1H NMR, IR and UV/visible spectroscopy.
