First evidence for the formation of technetium oxosulfide complexes: synthesis, structure and characterization?

Dalton Transactions Pub Date: 2012-03-20 DOI: 10.1039/C2DT30063J

Abstract

The reaction of tetrabutylammonium pertechnetate with bis(trimethylsilyl) sulfide in solution was studied by UV-Visible spectroscopy and mass spectrometry. Experimental results and density functional calculations provide the first evidence for the formation of a TcO₃S^? precursor. Larger scale synthesis afforded a solid that was characterized by EDX and XANES spectroscopy. XANES showed the presence of technetium in tetravalent state. EDX indicated the solid contained technetium, sulfur and oxygen.
