Electrochemistry and spectroelectrochemistry of polynuclear rhenium(III) chloride cluster complexes and their one-electron-reduction products in a basic room-temperature chloroaluminate molten salt

Redox chemistry of the [Re3(μ-Cl)3X9]3 − halides (X = Cl or Br); isolation and structural characterization of the [{Re3(μ-Cl)3Br6(H 2O)(μ-O)}2]2− cluster anion

“…electronic spectrum of 2a in the melt 6 is similar to that of the electrochemically prepared species in aqueous HCl, 5,7 whose anaerobic reaction with sulfuric acid produced the capped bridged µ 3 -sulfato derivative [Re 3 (µ-Cl) 3 Cl 3 (µ 3 -O 3 SO)] 3Ϫ containing the singly reduced Re 3 8ϩ cluster. 7 Reaction of Re 3 Cl 9 with aromatic amines of different basicity induces one-, two-or three-electron reduction producing complexes of the type [{Re 3 Cl 9Ϫn (amine) n } x ] (n = 1, 2 or 3) containing the Re 3 (9Ϫn)ϩ core.…”

“…generated electrochemically in aqueous 6 mol dm Ϫ3 HCl 5, 7 and similar to that prepared in a eutectic melt. 6 Complex 2a can also be obtained by using as reductants a mixture of Sn and SnCl 2 ؒ2H 2 O. The simultaneous presence of both reagents is necessary.…”

Reactions and speciation of technetium and rhenium in chloride melts: a spectroscopy study

“…Subsequent spectroscopic studies of rhenium in chloride systems have been mainly limited to the low-temperature ionic systems. Strubinger et al [22][23][24] have investigated rhenium(III) and (IV) species in room temperature were also reported in AlCl 3 -NaCl melts at 175 C. 25 In all the above work rhenium was introduced into the melts by dissolving various rhenium chloride salts, so there was no information on the formation of rhenium chlorides from other starting compounds, e.g., metal or oxides. Spectroscopic properties of technetium in molten salt systems (either high-or low-temperature) have not been previously reported.…”
