Abstract:
Discrete mononuclear TeCl⁻₅ anions were prepared for the first time in solid phase in association with bulky cations as tetrabutylammonium and tetraphenylphosphonium. The vibrational spectra imply tetragonal symmetry as for the isoelectronic TeF⁻₅ anion which is caused by a stereochemically active lone pair. A complete vibrational assignment is given and supported by a normal coordinate treatment for both ions. The significance of the resulting force constants is briefly discussed
