Tricarbonylrhenium(I) complexes with anionic ligands containing S and O donor atoms – potential radiopharmaceutical precursors

Equilibrium geometry of tricarbonylrhenium(I) thiosalicylate and of methylthiosalicylate has been determined by the X-ray diffraction studies as well as calculated by the semiempirical method using the PM3 functional basis set. Infrared spectra of the species have also been studied in the 4000−800 cm−1 range of wavenumbers. The experimental and theoretical data are in satisfactory agreement.
