摘要：
Rhenium(V) coordination compounds with pyroracemic acid and phenylglyoxylic acid thiosemicarbazones were synthesized for various metal-to-ligand ratios in 1–7 M hydrohalic acids. The composition and structure of the complexes were characterized using a set of physicochemical methods. The thermal stability of rhenium(V) complexes with pyroracemic acid and phenylglyoxylic acid thiosemicarbazones and rhenium(V) solvato complexes with pyroracemic acid thiosemicarbazone was studied thermogravimetrically. The thermolysis mechanism for the complexes was determined as follows: elimination of outer-sphere water, decarboxylation, and dehalogenation.
