An S = 3 cyanide-bridged tetranuclear FeIII2Ni II2 square that exhibits slow relaxation of magnetization: Synthesis, structure and magnetic properties

The reaction of [NiII(dpa)2(solvent)]2+ (dpa = 2,2?-dipyridyl amine) with [Bu4N][(pzTp)Fe III(CN)3] (Bu4N+ = tetrabutylammonium cation; pzTp = tetrakis(pyrazolyl)borate) in MeOH affords a tetranuclear cyano-bridged cluster, [(pzTp)2Fe2Ni 2(dpa)2(CN)6](ClO4) 2¡¤2CH3OH¡¤6H2O (1). Single-crystal X-ray analysis reveals that it is a quasi-square structure with the lateral distance being ca. 5.1 A, in which two opposing dpa-ligated Ni II ions (S = 1) are linked through cyanide bridges to two pzTp-ligated FeIII (S = 1/2) centers at the corner sites. Magnetic studies for complex 1 show ferromagnetic coupling (J/k = 10.12 K) giving rise to an S = 3 ground state; ac magnetic susceptibility measurements performed on sample 1 showed evidence of the slow relaxation effects possibly associated with single-molecule magnet behavior.

Palladium-Catalyzed Amination of Aryl Sulfides and Sulfoxides with Azaarylamines of Poor Nucleophilicity

The amination of aryl sulfides and sulfoxides with azaarylamines is investigated using a palladium-N-heterocyclic carbene (NHC) complex. Because azaarylamines are less nucleophilic than anilines, more reactive diaryl sulfides and sulfoxides are found to be suitable coupling partners that liberate better leaving arenethiolate or arenesulfenate anions, instead of aryl methyl sulfides as reported previously.

Mononuclear copper(II) complexes with quinolones and nitrogen-donor heterocyclic ligands: Synthesis, characterization, biological activity and interaction with DNA

The neutral mononuclear copper(II) complexes with the quinolone antibacterial drugs, pipemidic acid and N-propyl-norfloxacin, in the presence or absence of nitrogen-donor heterocyclic ligands, 2,2?-bipyridine, 1,10-phenanthroline or 2,2?-dipyridylamine, have been prepared and characterized spectroscopically. The interaction of copper(II) with the deprotonated quinolone ligand leads to the formation of the neutral mononuclear complexes of the type [Cu(quinolone)2(H2O)] (1)-(2) while the presence of the N-donor ligand leads to the formation of the neutral mononuclear complexes of the type [Cu(quinolone)(N-donor)Cl] (3)-(8). In all the complexes, copper(II) is pentacoordinate having a distorted square pyramidal geometry. The electron paramagnetic resonance spectra of 1 and 2 are typical of mononuclear Cu(II) complexes, while for the mixed-ligands complexes 3-8 a mixture of dimeric and monomeric species is indicated. The interaction of the complexes with calf-thymus DNA has been investigated with diverse spectroscopic techniques and has shown that the complexes can be bound to calf-thymus DNA by the intercalative mode. The antimicrobial activity of the complexes has been tested on three different microorganisms. All the complexes show an increased biological activity in comparison to the corresponding free quinolone ligand.

Study of the influence of the molecular organization on single-layer OLEDs’ performances

We have synthesized three new silole derivatives with incrementally flexible structure to tune their packing ability and therefore study the influence of the molecular organization in single-layer OLEDs. This architecture was chosen since the absence of organic layers interfaces allows a better evaluation of the role of the molecular arrangement in the active layer. The examination of the EL properties gives evidences of the prominent role of the molecular organization on the OLED efficiency. A crystalline-like organization of the molecules allows high current density but low luminance efficiency since an excessive electron current flow is involved compared to the hole one, and the recombination rate is poor. On the contrary, disordered assemblies of molecules allows better performances by avoiding unfavourable pi-stacking, while keeping good intermolecular orbital overlaps to support charge carrier transport.

Half-Sandwich Osmium(II) Complexes with Bidentate N,N-Chelating Ligands and Their Use in the Transfer Hydrogenation of Ketones

The reaction of appropriate N,N-bidentate ligands with the [(eta6-p-cymene)Os(mu-Cl)Cl]2dimer (p-cymene = C10H14), followed by metathesis reaction with NH4PF6, gave the new osmium(II) arene complex salts [(eta6-p-cymene)OsCl(C5H4N-2-CH=N?R)]PF6, where [R = tert-butyl (1), isopropyl (2), 2,6-dimethylphenyl (3), or 2,6-diisopropylphenyl (4)]. The dimer was also reacted with the N,N?-bidentate ligands di-(2-pyridyl)amine (5), 4-phenyl-3,6-di(2-pyridyl)pyridazine (6), 4,4?-di-tert-butyl-2, 2?-bipyridine (7), and 5,5?-dimethyl-2,2?-bipyridine (8). In addition, the reaction of the precursor [(eta6-C6H6)Os(mu-Cl)Cl]2with the N,N?-bidentate ligands gave [(eta6-C6H6)OsCl(N,N)]2where N,N = 4,4?-di-tert-butyl-2,2?-bipyridine (9), 5,5?-dimethyl-2,2?-bipyridine (10), 3,6-bis(2-pyridyl)-4-phenyl pyridazine (11), or di-(2-pyridyl)amine (12). The compounds were characterized by using1H and13C NMR, UV/Vis, FTIR spectroscopy and elemental analysis. The single-crystal X-ray structures for compounds 1, 4, 8, 10, 11, and 12 showed that the osmium(II) complexes adopted the classical three-legged piano stool geometry. These osmium(II) compounds were found to be effective catalysts for the transfer hydrogenation of ketones into alcohols with NaOH as base and 2-propanol as the solvent and hydrogen source. A range of cyclic, aromatic, and aliphatic ketones was studied and good turnover numbers achieved.
