On the interaction of triazole complexes of rhenium (5) with since organic solvents

Interaction of rhenium (5) complexes of the composition [ReO(OH)LX2(H2O)], where L-1,2,4-triazole, and X-Cl, Br, with certain organic solvents was studied. It is shown that solvent molecules are substituted for coordinated molecule of water, but do not replace molecules of 1,2,4-triazole and halidoligands from internal sphere. Complexes of the composition [ReO(OH)LX2S], where S-DMFA, DMSO, Py and CH3CN, were isolated and characterized. It is shown that heating of the complexes of the first stage of thermolysis removes molecules of organic solvents and water and dimmer compounds of the composition [Re2O3L2X4] are formed. It is ascertained that the temperature of organic molecule removal from the complexes decreases in the series: Py≥CH3CN>DMFA>DMSO
