Contribution to the coordination chemistry of technetium

Abstract

The universal use of radiophamaceuticals labeled with^99mTc has led to the development of many Tc complexes containing^99mTc⁴⁺ or⁹⁹Tc⁵⁺. In order to assess the correlation between the physiological properties and the chemcial structure of a^99mTc complex, milligramm amounts of the corresponding long-lived^99gTc compound have to be synthesized and analyses. This report describes the synthesis and characterization of several new technetium complexes with ligands containing N, O and S as donor atoms.
