Technetium complexes with thioether ligands—I. Cationic technetium(III) complexes containing tetradentate thioether/monothiole ligands; X-ray structure analysis of bis(benzenethiolato)(5,8,11,14-tetrathiaoctadecane)technetium(III)hexafluorophosphate
摘要:
Cationic technetium(III) complexes containing both tetradentate thioether and monothioles, [Tc(''S4'')(SR)2]PF6 (''S4'': 3,6,9,12-tetrathiatetradecane, 5,8,11,14-tetrathiaoctadecane; SR : monodentate thiolates), were prepared starting from TcO4- and characterized by elemental analysis and spectroscopic methods. Bis(benzenethiolato)(5,8,11,14-tetrathiaoctadecane)technetium(III)hexafluorophosphate was characterized by single-crystal X-ray structural analysis (R = 0.084). In the complex the technetium is centred in a heavily distorted octahedron. The benzenethiolate ligands are coordinated in the cis-configuration.
