Peroxomanganese(iii) adducts have been postulated as important intermediates in manganese-containing enzymes and small molecule oxidation catalysts. Synthetic peroxomanganese(iii) complexes are known to be nucleophilic and facilitate aldehyde deformylation, offering a convenient way to compare relative reactivities of complexes supported by different ligands. In this work, tetradentate dipyridy...

The results of quantum-chemical simulation the molecular structure and excited states some mesogenic europium(III) (Eu(III)) complexes liquid-crystalline (LC) (co)polymers are provided. These objects represent components currently relevant composites with a hybrid structure, unique optical magnetic properties for optoelectronic devices. relationships between geometric parameters, LC properties,...

The schiff base ligand was prepared from furfuraldehyde with 4-amino-5-mercapto-5triazole and characterised. The metal complexes of Ti(III),V(III),Mn(III),Co(III) and Ru(III) derived from this ligand were characterised by elemental analyses, molar conductance,magnetic measurements, infra red 1H NMR & electronic spectral data. Based on these studies octahedral structures have been assigned to th...

Recent spectroscopic data suggest that the Co(III) site in Co-containing nitrile hydratase is ligated to carboxamido nitrogens and thiolato sulfurs and most possibly one or more of the bound thiolates exist as sulfenato and/or sulfinato groups. The absence of any Co(III) complex with such coordination makes it quite difficult to predict the reactivity of this kind of Co(III) site. In this paper...

The complexes of chromium(III) ion formed by salicylic acid, SA(H(2)L), and its derivatives (H(2)L): 5-nitrosalicylic acid (5-NSA), 5-sulphosalicylic acid (5-SSA) were investigated by means of potentiometry and spectroscopy, at 25 degrees C and in ionic strength of 0.1 M KNO(3) and 0.1 M KCl, respectively. Over the acidic pH range, the coordination of Cr(III) ion to SA and its derivatives in 1 ...

Metal acetylacetonates belong to the β-diketonate family and are considered as classics among precursors for metal–organic chemical vapor deposition (MOCVD). The success of film preparation is crucially dependent on volatilization thermodynamics used. Data metal in huge disarray. We amassed analyzed experimental data pressures enthalpies entropies fusion, vaporization, sublimation acetylacetona...
