 Title      
 Abstract    Molecular Vibration Analysis of the Hexathiometadiphosphatanion P2Sl~~ A normal coordinate analysis for the Hexathiometadiphosphate anion P2Sj;~ was performed, based on a simple initial force field. The force field was refined by adjusting the symmetry force constants to approximate the observed frequencies. The final force field, potential energy distribu­ tion (PED) and mean amplitudes of vibration are also given. Based on the normal coordinate analysis a new assignment of the P2Sg~ frequencies is proposed.

 Title    Zur Existenz diskreter TeCl 5 -Ionen On the Existence of Discrete TeCl s ~ Ions  
 Abstract    Discrete mononuclear TeCl 5 " anions were prepared for the first time in solid phase in associa-tion 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.

The force field is refined by adjusting the symmetry force constants to fit the observed frequencies. The final force field, potential energy distribution (PED), mean amplitudes of vibration and the standard thermodynamic functions from spectroscopic data are also given for the title compounds.
