The IR and Raman spectra of the three complexes were measured at room temperature. Using the molecular parameters of the X-ray determinations normal coordinate analyses based on a modified valence force field have been performed and the normal modes o f vibration are assigned. With a set of 25 force constants and taking into account the innerligand vibrations a good agreement between observed and calculated frequencies has been achieved. The valence force constants of the X-Os-X axis are fd(OsCl) = 1.77, fd(OsBr) = 1.48, fd(OsI)o= 1.0 mdyn/A, of the X'-Os-O* axes are fd(O sCl') = 1.88, fd(OsBr') = 1.6, fd(OsI') =1.1 mdyn/A and fd(OsO*) ranges from 2.7 to 2.8 mdyn/A.

The hepta-coordinated Nb(V) atom is surrounded by four isoindole nitrogen atoms (Niso) of the pc2~ ligand, two fluorine atoms and one oxygen atom in a distorted square-base-trigonal-cap poly­ hedron. Nb(V) is displaced out o fothe centre of the (N,.s")4 plane (Ct(N,.so)) towards the acido ligands (d(Nb-Ct(Niso)) = 1.241 A). The average (Nb-NIJO), (Nb-F), and (Nb-O) distances are 2.300, 1.957, and 1.720(5) A, the (F-Nb-F) and the average (O-Nb-F) angles are 79.8(2) and 91.8°, respectively. The pc2_ ligand is concavely distorted. Typical 7r-7r*-transitions of the pc2~ligand are observed in the UV/Vis spectra at ca. 14500 and 29300 cm-1 . Vibration frequencies t/asiS(M-X), ^(M-O) and (5(X-M-0) have been assigned.

Based on the molecular parameters of the X-ray determinations the IR and Raman spectra for the anions of 1 and 2 have been assigned by normal coordinate analysis. Due to the mutual trans influences the valence force constants of asymmetrically coordinated octahedral axes F*-Os-Cl' differ from those of the symmetric F-Os-F axes. The data are for 1: fd(OsF*) = 3.95, fd(OsF) = 4.07, fd(OsCl') = 2.51 and for 2: fd(OsF*) = 3.45, fd(OsF) = 3.97, fd(OsCl') = 2.42 mdyn/A.

 Title    Darstellung und spektroskopische Charakterisierung der Trihalogenphosphonium-Salze PHaI3X+MF6-(Hal = Cl, Br; X = H, D; M = As, Sb)  
 Abstract    Preparation and Spectroscopic Characterization of the Trihalogenophosphonium Salts PHal3X+MF6-(Hal = Cl, Br; X = H, D; M = As, Sb) M = As, Sb) are prepared at 213 K by protonation of the phosphortrihalides in the superacidic media XF/MF5. The salts are characterized by 31P, MS, IR and Raman spectroscopy.

 Title    Darstellung, Schwingungsspektren und Normalkoordinatenanalyse der  
 Abstract    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
