摘要
Rhenium(V) complexing with mono- and bisbenzoylthiosemicarbazones has been studied as a function of hydrohaloic acid (Mal HCl, HBr) concentration. Given a high acid concentration (6 M HCl, 7 M HBr). stable coordination compounds with bidentate- or tridentate-coordinated semicarbazone are formed depending on the reaction conditions. At lower acid concentrations, stable binuclear and hydroxooxo complexes are formed. The composition and structure of the complexes have been determined using elemental analysis, IR spectroscopy, and conductometry. A thermal study of the complexes has been carried out.
