Pure (TBA)[TcOI 4 ] is prepared from (TBA)[TcOCl 4 ] by ligand exchange reaction with Nal in acetone. The vibrational spectra indicate C 4v  symmetry for the complex ion. On excitation with the 514.5 nm line of an Ar-laser a resonance Raman spectrum is obtained showing v(TcO) = 996 cm -1  and four of its overtones, symmetrically surrounded by groups of bands arising as well from the sums as from the differences of frequencies with the other fundamentals. In contrast to the ligand exchange reaction the reduction of Tc0 4 - with conc. HI yields products always contaminated with polyiodides. The extremely strong Raman scatterer (TBA)l 3  is detected by a characteristic doublet at 111 and 116 cm -1  and even small amounts of it cover the Raman spectrum of (TBA)[TcOI 4 ].
