Self-assembly of arene ruthenium acylpyrazolone fragments to tetranuclear metallacycles. Molecular structures and solid-state (15)N CPMAS NMR correlations.
Reactions of [(η(6)-cymene)Ru(μ-Cl)Cl]2 with acylpyrazolone ligands HQ' (HQ' in general; in detail, HQ(CH2Cl) = 2-chloro-1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone), HQ(hex) = 1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)heptan-1-one), HQ(nPe) = 1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3,3-dimethylbutan-1-one)), in the presence of base, gave the corresponding [(η(6)-cymene...
متن کاملRevealing molecular self-assembly and geometry of non-covalent halogen bonding by solid-state NMR spectroscopy.
We report a new spectroscopic fingerprint of intermolecular contacts in halogen bond-driven self-assembling aggregates and a precise determination of intermolecular NI distances in microcrystalline samples.
متن کاملAccurate measurement of 13C-15N distances with solid-state NMR.
Solid-state NMR technique for measuring distances between heteronuclei in static powder samples is described. It is based on a two-dimensional single-echo scheme enhanced with adiabatic cross polarization. As an example, the results for intramolecular distances in alpha-crystalline form of glycine are presented. The measured NMR distances (13)C(alpha)-(15)N and (13)C(')-(15)N are 1.496+/-0.002 ...
متن کاملCombining coordination and hydrogen-bonds to form arene ruthenium metalla-assemblies
Three ureido-pyrimidone derivatives (N-LH) were used to generate in combination with four dinuclear arene ruthenium clips, (p-cymene)2Ru2(OO∩OO)Cl2 (OO∩OO 1⁄4 oxalato, 2,5-dioxido-1,4-benzoquinonato, 2,5-dichloro-1,4-benzoquinonato, 5,8-dioxido-1,4-naphtoquinonato), twelve cationic arene ruthenium metalla-cycles of the general formula [(p-cymene)2Ru2(OO∩OO)(N-L)2]2(CF3SO3)4. The ureidopyrimidon...
متن کاملDesigning the Host-Guest Properties of Tetranuclear Arene Ruthenium Metalla-Rectangles to Accommodate a Pyrene Molecule
Cationic tetranuclear arene ruthenium complexes of the general formula [Ru4(p-cymene)4(N N)2(dhnq)2] comprising rectangular structures are obtained in methanol from the reaction of the dinuclear arene ruthenium precursor [Ru2(p-cymene)2(dhnq)2Cl2] (dhnq = 5,8-dihydroxy-1,4-naphthoquinonato) with pyrazine or bipyridine linkers [N N = pyrazine, 1; 4,4 -bipyridine, 2; 1,2-bis(4-pyridyl)ethylene, 3...
