Soft chemistry route to rhenium-based materials

Kessler, VG; Seisenbaeva, GA; Drobot, DV


The so called soft chemistry approach is usually based on hydrolytic or pyrolytic decomposition of the complexes of metals with organic ligands. The methoxides of rhenium (I), rhenium and molybdenum (II) and rhenium and tungsten (III) were prepared by anodic oxidation of rhenium metal in methanol in the presence of LiCl as electrolyte and methoxides of countermetals. Acetylacetonate, Re2O5(acac)(2) (IV) was obtained by interaction of Re2O7 and Hacac in toluene. I and III are insoluble in common organic solvents and air stable in contrast to highly soluble and air and moisture sensitive II. IV is insoluble in hydrocarbons and dissolves in ethers with decomposition. All these compounds are volatile at reduced pressure and decompose in inert atmosphere into mixed low-valent oxides or, in case of IV, into rhenium metal.
