On heating the tetraethylammonium salt of [IrCl6]2- with trifluoroacetic acid the edge sharing bioctahedral anion [Ir2Cl10]2- is formed, the IR and Raman spectra of which are assigned according to point group D2h. Normal coordinate analyses, based on a general valence force field, for [M2X10]2-, M = Re, Os, Ir, Pt; X = Cl, Br have been performed, resulting in a good agreement of the calculated frequencies with the bands observed in the IR and Raman spectra. Due to the stronger bonding of the terminal as compared to the bridging ligands, the valence force constants fd(MXt) are significantly higher than fd(MXb).
