in present studies the synthesis, characterization and biological properties ofoxovanadium(iv) coordination compounds of 4[n-(4′-ethylbenzalidene)amino] antipyrinethiosemicarbazone (ebaapts) and 4[n-(2′,4′-dimethylbenzalidene)amino] antipyrinethiosemicarbazone (dmbaapts) with the general composition vox2l (x = c1-, br-, i-, no3-or ncs-) and vo(cio4)2(l)h2o (l = ebaapts or dmbaapts) are describe...

We perform first-principles density-functional theory calculations to investigate the structural and electronic properties and the formation energies of nitrogen vacancies in wurtzite InN. We report an extensive and systematic study of the favorable atomic and electronic configurations of up to six vacancies in large supercells. The isolated vacancy acts as a donor in a p-type material where th...

The synthesis and photophysical properties of the Eu(iii) complex , based on the use of 1,10-phenanthroline (phen) as a combined sensitizing antenna and a transition metal ion coordinating ligand, is described. The long-wavelength Eu(iii) emission from this complex was found to be highly pH sensitive, giving rise to a 'off-on-off' pH profile with maximum emission occurring within the physiologi...

PSII antenna size heterogeneity has been intensively studied in the past. Based on DCMU fluorescence rise kinetics, multiple types of photosystems with different properties were described. However, due to the complexity of fluorescence signal analysis, multiple questions remain unanswered. The number of different types of PSII is still debated as well as their degree of connectivity. In Chlamyd...

the vo(iv) complexes of tridentate ono schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by ir, uv–vis and elemental analysis. electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. a good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...

Ru=O complexes have been demonstrated to be competent oxidants for oxidation of saturated hydrocarbons and epoxidat ion of alkenes . Photoexcitation of transdioxoosmium(V1) gives rise to super-oxidizing complexes having EO >2.2 V vs. n.h.e.. Some cationic RuZN and OsZN complexes are good model system for study of the mechanism of metalcatalysed oxidation of ammonia to nitrite and activation of ...

The title compounds react with iodine to give the iodinecarbonyl complexes (*7-C5H5)Co(CO)l2 and (j?-EtMe4C5)Co(CO)l2. The reactions of the same compounds with the cyanogen halides X C N (X = Br or I) give rise to the formation of mixed cyanocarbonyl complexes (^-C5H5)Co(CO)(CN)X and (7?-EtMe4C5)Co(CO)(CN)X (X = Br or I) respectively. The compounds have been characterized by elemental analyses ...

We report the formation of dinuclear complexes from, and photochemical oxidation of, (CH3)3-Pt(IV)(N^N) (N^N = 1,2-diimine derivatives) thiophenolate ligands to analogous sulfinates (CH3)3Pt(N^N)(SO2Ph) structural, spectroscopic, theoretical studies latter revealing tunable photophysics depending upon ligands. Electron-rich thiolate conjugated 1,2-diimines encourage thiolate-bridged complexes; ...
