 Title    Darstellung, Kristallstruktur und Schwingungsspektren von Rubidiumperoxoniobat (Rb3NbOs) Preparation, Crystal Structure, and Vibrational Spectra of Rubidiumperoxoniobate (Rb3N b 0 8)  
 Abstract    The crystal structure of Rb3N b 0 8 (SG I42m, Nr. 121) has been determined on single crystals to a final R = 0.041. The structure is isotypic to the K3C r 0 8 type. Vibrational spectra of the title compound have been recorded on powdered samples and are discussed with respect to the internal vibrations of the peroxo-group and the dodecahedral N b 0 83-ion. The stretching vibrations of the 0 22~ groups are found at 838 (Raman) and 813 cm _1(IR). A factor group analysis for the K3C r0 8 type is given.

The average B-B distan­ ces are nearly equal (1.733 Ä (1), 1.728 A (2), 1.728 A (3)) while the B-X distances increase (1.762 A (1), 1.912 A (2), 2.120 A (3)). Using the molecular parameters, normal coordinate analyses have been performed and a good agreement of observed and calculated frequencies of 11B and 1 'B labelled derivatives has been achieved. The valence force constants fd(BB) and fd(BX) of [B6X6]" are 1.17 and 4.17 (X = Cl), 1.18 and 3.34 (Br) and 1.18 and 2.60 mdyn/A (I), respectively.

 Abstract    The crystal structures of [(C5H5N)iC H 2][OsCl4(ox)] (monoclinic, space group I2/m, a = 10.260(5), b = 13.841(5), c = " 12.273(5) Ä, ß = 92.050(5)°, Z = 4), [(C5H5N)2CH2j[O sBr4(o x)]H 20(m onoclinic, space g ro u p P 2 ,/n ,a = 11.666(3),b = 11.591(5), c = 14.926(2) A, ß = 102.45(2)°, Z = 4) and [P(C6H5)4M O sI4(ox)]-2CH2C12 (triclinic, space group P i, a = 14.597(2), b = 11.9185(9), c = 22.5624(14) A, a = 80.284(8), ß = 78.903(8), 7 = 69.432(8)°, Z = 2) have been determined by single crystal X-ray diffraction analysis. 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.

 Abstract    The preparation of the N,N-Bistrifluoromethylhydroxylammonium hexafluorometallates (CF3)2N(X)OX+MF6~ (X = H, D; M = As, Sb) is reported. The new compounds were cha­ racterized by IR, Raman, Mass, 'H , ,9F and l3C NM R spectroscopy. In addition we present our approach to the preparation of H-subsituted N,N-Bistrifluoromethylhydroxylammonium hexafluorometallates (C F ^ N (Y)O H +M F6~ (Y = C H 3, Cl, F; M = As, Sb).
