Optimum conditions have been found for the synthesis of peroxide-containing supramolecular structures through the reactions of Zn-Al layered double hydroxide (LDH) and its modified analogues with hydrogen peroxide solutions. The supramolecular structures based on Zn-Al LDH are stable and contain 15% active oxygen (31.8% H2O2). A peroxide formation ...

The reaction of 45% fluorosilicic acid with methanol solutions of several 2-substituted anilines(L) gave hexafluorosilicates (LH)2SiF6. The products were studied by elemental analysis, IR spectroscopy, mass spectrometry, and thermogravimetry. The solubility and the hydrolytic stability of the salts were estimated. The structure of the complex [CH3O...

The tetradentate-ligand Schiff base derived from salicylaldehyde and 1,2-diaminoethane has been synthesized. The stability constants and thermodynamic values for the complexation between ZnCl2, Cu(NO3)2, and AgNO3 salts and the ligand in 80% dioxane-water were determined by conductance measurements. The order of the formation constant for complexes...

We present the results of the investigation of the ZrO2-FeO system under an inert atmosphere. We have refined the position of the eutectic point, which lies at 1332 ± 5°C and 10.3 ± 0.6 mol % ZrO2. The iron oxide solubility boundaries in zirconium dioxide have been determined over a wide temperature range taking into account the polymorphism in ZrO...

A new ammonium gallium hydroxyphosphate (NH4)Ga(OH)PO4 was synthesized under mild hydrothermal conditions (200°C, τ = 168 h). The equimolar content of Ga and P was determined by chemical analysis and electron probe X-ray microanalysis. The presence of NH4 and OH groups was demonstrated by IR and Raman spectroscopy. An ab initio model of the crystal...
