Synthesis and characterization of bis (acetylacetonato kappa-O, O?) [zinc(ii)/copper(ii)] hybrid organic-inorganic complexes as solid metal organic precursors

We have synthesized novel metal organic hybrid mixed compounds of bis (acetylacetonato kappa-O, O?) [zinc(ii)/copper(ii)]. Taking C10H14O4Zn0.7Cu0.3 (Z0.7C0.3AA) as an example, the crystals are composed of Z0.7C0.3AA units and uncoordinated water molecules. Single-crystal X-ray diffraction results show that the complex Z0.7C0.3AA crystallizes in the monoclinic system, space group P21/n. The unit cell dimensions are a = 10.329(4) A, b = 4.6947(18) A, and c = 11.369(4) A; the angles are alpha = 90, beta = 91.881(6), and gamma = 90, the volume is 551.0(4) A3, and Z = 2. In this process, the M(ii) ions of Zn and Cu mix and occupy the centers of symmetrical structural units, which are coordinated to two ligands. The measured bond lengths and angles of O-M-O vary with the ratio of metal species over the entire series of the complexes synthesized. The chemistry of the as-synthesized compounds has been characterized using infrared spectroscopy, mass spectroscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy analysis, and the morphology of the products has been characterized using scanning electron microscopy. The thermal decomposition of the Z0.7C0.3AA composites measured by thermogravimetric analysis suggests that these complexes are volatile. The thermal characteristics of these complexes make them attractive precursors for metal organic chemical vapor deposition.

ALLYLIC VERSUS VINILIC OXIDATION OF CYCLOHEXENE PROMOTED BY TRANSITION METAL beta-DIKETONATES

We report the cyclohexene oxidation by molecular oxygen in the presence of several metal beta-diketonates. The catalytic conditions used showed an allylic/vinilic oxidation (ao/av) ratio equal 1.5. The complexes M(l)n were used with the metal ions Co(III), Ni(II), Pd(II), Cu(II), chelated with acetylacetone (AcAc), benzoylacetone (BeAc) and dibenzoylacetone (BeBe) as ligands. The oxidation selectivity of the studied system suggests a different allylic/vinylic pathway compared with that observed inprevious reports.

Spin-orbit effects on hyperfine coupling tensors in transition metal complexes using hybrid density functionals and accurate spin-orbit operators

A coupled-perturbed Kohn-Sham treatment for the calculation of hyperfine tensors has been implemented into the MAG-ReSpect program. It treats spin-orbit contributions to hyperfine tensors by a combination of accurate and efficient approximations to the one- and two-electron spin-orbit Hamiltonians: (a) by the all-electron atomic mean-field approximation, and (b) by spin-orbit pseudopotentials. In contrast to a previous implementation, the code allows the use of hybrid functionals and lifts restrictions in the orbital and auxiliary basis sets that may be employed. Validation calculations have been performed on various transition metal complexes, as well as on a series of small diatomic molecules. In the case of a series of copper(II) complexes, the spin-orbit contributions are large, and their inclusion is essential to achieve agreement with experiment. Calculations with spin-orbit pseudopotentials allow the efficient simultaneous introduction of scalar relativistic and spin-orbit effects in the case of light nuclei in the neighborhood of heavy atoms.

Creation of RT-FM in CdO nanocrystalline powder by codoping with Cu and Gd: Effect of annealing in hydrogen atmosphere

Cadmium oxide codoped with Cu and Gd ions powders were synthesised by simultaneous thermal co-decomposition of a mixture of cadmium acetate dihydrate, bis(acetylacetonato)copper, and tris(acetylacetonato)gadolinium(III) complexes. The mass ratio of Cu/Cd is fixed while the Gd/Cd mass ratio varied systematically. The purpose of the present study is to prepare powders having room temperature ferromagnetic (RT-FM) properties. Thus, an amount from each powder was annealed in hydrogen atmosphere in order to study its influence on the magnetic properties. X-ray fluorescence (XRF) and X-ray diffraction (XRD) methods confirm the purity and the formation of single nanocrystalline structure of the as-prepared powders, thus, both Cu and Gd ions were incorporated into CdO lattice forming solid solutions. Magnetic measurements reveal that all doped CdO powders gained paramagnetic (PM) properties where the susceptibility increases linearly with increasing dopant Gd content; the measured effective magnetic moment of doped Gd3+ was 7muB. Furthermore, the created RT-FM is dependent on the Gd% doping level. Also, it was found that the hydrogenation of the powders slightly enhances their PM properties and strongly enhances or creates RT-FM. For hydrogenated CdO powder doped with 3.1% Gd, the coercivity (Hc), remanence (Mr), and saturation magnetization (Ms) were 283.2 Oe, 2.04 memu/g, and 6.67 memu/g, respectively. Also, under hydrogenation, the values of Hc, M r, and Ms were increased by ?145%, 476%, and 131%, respectively in comparison with as prepared. Thus it was proved, for the first time, the possibility of production of CdO with RT-FM, where magnetic characteristics can be tailored by doping and post treatment under H2 atmosphere, thus a new potential candidate to be used as a dilute magnetic semiconductor (DMS).

Total synthesis of apicularen a through transannular pyran formation

A macrocyclization-transannulation strategy is the crux of an efficient total synthesis of the benzolactone enamide apicularen A (see scheme; Bn = benzyl). Key steps include a four-component coupling, a Stille cross-coupling to introduce the aromatic moiety, and the formation of the enamide from a hemiaminal. The size-selective macrolactonization of the ethoxyvinyl ester shown was followed by transannular etherification in excellent yield.

Structure of bis[ethyl (trifluoroacetyl)acetato]copper(II) and its adduct with 4-(dimethylamino)pyridine: EPR and X-ray study

Bis[ethyl (trifluoroacetyl)acetato]copper(II), [Cu(etfac)2], has been prepared and studied by X-ray crystallography and EPR spectroscopy. The complex is centrosymmetrical and crystallizes in the P21/c space group with two formula units per unit cell. After dissolving of the complex in solid matrix or in suitable solvents some changes are detected in the EPR spectra and are discussed. The EPR spectra of the complex magnetically diluted in the corresponding Pd(II) complex reveal the presence of only one paramagnetic species further denoted as B. However, EPR spectra measured in solution indicate the presence of two different paramagnetic species: (i) non-distorted parent species B, and (ii) rhombic-distorted species A, which prevail in solutions. The A:B species ratio is a function of the solvent and temperature. The [Cu(etfac)2] adduct with 4-(dimethylamino)pyridine has also been studied and found to crystallize in the C2/c space group. The adduct EPR spectrum monitored in solution shows the presence of only one paramagnetic species.

Wavelength dependent photochemical charge transfer at the Cu2O-BiVO4 particle interface-evidence for tandem excitation

The understanding of the photochemical charge transfer properties of powdered semiconductors is of relevance to artificial photosynthesis and the production of solar fuels. Here we use surface photovoltage spectroscopy to probe photoelectrochemical charge transfer between bismuth vanadate (BiVO4) and cuprous oxide (Cu2O) particles as a function of wavelength and film thickness. Optimized conditions produce a -2.10 V photovoltage under 2.5 eV (0.1 mW cm-2) illumination, which suggests the possibility of a water splitting system based on a BiVO4-Cu2O direct contact particle tandem.

Compositionally tunable Cu2ZnSn(S1-xSe x)4 nanocrystals: Probing the effect of Se-inclusion in mixed chalcogenide thin films

Nanocrystals of multicomponent chalcogenides, such as Cu 2ZnSnS4 (CZTS), are potential building blocks for low-cost thin-film photovoltaics (PVs). CZTS PV devices with modest efficiencies have been realized through postdeposition annealing at high temperatures in Se vapor. However, little is known about the precise role of Se in the CZTS system. We report the direct solution-phase synthesis and characterization of Cu 2ZnSn(S1-xSex)4 nanocrystals (0 ? x ? 1) with the aim of probing the role of Se incorporation into CZTS. Our results indicate that increasing the amount of Se increases the lattice parameters, slightly decreases the band gap, and most importantly increases the electrical conductivity of the nanocrystals without a need for annealing.
