| The IR and Raman spectra of the ten brom o-iodo-rhenates(IV) [ReBr"I6_"]2 -, n = 0 -6 , including the geometrical isomers for n -2,3,4, have been recorded at 80 K. The vibrational spectra are com pletely assigned according to point groups O h, D 4h, C4v, C3v, and C2v, as supported by normal coordinate analyses based on a general valence force field. Due to the different mms-influences Br < I in asymmetric axes B r '-R e -I ', the R e -I ' bonds are strengthened and the R e -B r ' bonds are weakened, as indicated by valence force constants, for R e -I ' on average 8,5% higher and for O s -B r ' 8,3% lower, as compared with the values calculated for symmetric I -R e -I and B r -R e -B r axes, respectively | | | |
