 Title    Oxidative Addition Reactions of P(CN)" P(NCO)3 and P(NCS), to (i/5-C5Me5 )Co(CO)2  
 Abstract    The phosphorus pseudohalogens P(CN)3, P(NCO)3 and P(NCS)3 react with (?/5-C5Me5)C o(C O)2 to give the complexes (?75-C;Me5)Co(CO)XPX2 (X = CN, NCO, NCS). All the compounds are characterized by elemental analysis, IR. electronic and 'H NMR spectra.

 Title    ReCl5 * OPCl3; IR-Spektrum und Kristallstruktur ReCl5 -O PCl3; IR Spectrum and Crystal Structure  
 Abstract    Single crystals of ReCl5 • OPCl3 were obtained by cooling a saturated solution of rheniumpen­ tachloride in phosphorylchloride. It formes black needles, which are extremely sensitive to mois­ ture. In the IR spectrum v(PO) is shifted downwards by 140 cm-1 in comparison with liquid POCl3, indicating coordination via oxygen. The crystal structure was solved and refined from X-ray diffraction data (space group Pnma, four formula units per unit cell, a = 1629, b = 790, c = 877 pm, 902 observed, independent reflexions, R = 0.040). The complex forms discrete molecules ReCl5 • OPC1, with symmetry Cs (m). Bond lengths are Re —O — 214 pm and P —O = 146 pm, the angle Re —O —P is 143°.

 Abstract    Osmium pentachloride reacts with NO forming the com plex N O [O s(N O)C l5], which when treated with (PPh3M e)C l yields PPh3M e[O s(N O)C l5] and nitrosyl chloride. The thionitrosyl com plex A sP h 4[O s(N S)C l5] is prepared by the reaction of

 Title    Darstellung, n B-NMR-und Schwingungsspektren der oktaedrischen closo-Boratanionen B6X62-; X = H, Cl, Br, I  
 Abstract    On treatment of N a2BhHft with halogens in aqueous alkaline solution, the hexahalogenoborates BftX 62_, X — Cl, Br, I, are formed. Their octahedral structure is proved by n B N M R spectro­ scopy. The chemical shifts in relation to B F 3 O E t2 increase within the series H (— 13.5) < Cl (—17.4) < Br (—18.5) < I (— 27.5 ppm). The IR and Raman spectra are assigned according to point group O h. The internal vibrations o f the B 6-cage, observed in the range 750—1250 cm ' 1 at nearly unchanged positions, are distinguishable from vibrations m ainly originating from motions o f the X 6-shell against the rigid B 6-cluster.

 Title    Darstellung, n B-NMR-und Schwingungsspektren isomerenreiner Halogenohydrododecaborate X"B12H12 _n2_; X = CI  
 Abstract    , n = 1—3; X = Br, n = 1,2; X = I, n = 1 Preparation, nB NMR and Vibrational Spectra of Pure Isomeric Halohydrododecaborates X"B12H 12_"2-; X = Cl, n = 1 -3 ; X = Br, n = 1,2; X = I, n = 1 Pure isomers of X"B12H 12_"2_; X = Cl, Br, I are isolated by ion exchange chromatography on diethylaminoethyl cellulose. The structures are determined by " B and " B l'H jN M R spectro­ scopy. With X = Cl, Br the signal of ipso-B atomes is shifted to lower, with X = I to higher field compared with B 12H 122~. The resonances of B-atoms influenced by the antipodal effect are ob­ served at high field, increasing within the series I< B r< C l. The chemical shifts are explained by the anisotropy effect and by the paramagnetic term due to different —I and +M effects of the halogens. In agreement with theoretical predictions the substitution of B 12H 122~ with chlorine proceeds successively at vicinal positions B (l) —B(2) —B(3). The IR and Raman spectra of 1-XBi2H u2~ show in the region 175 — 380 cm -1 two characteristic bands shifting to lower frequen­ cies in the series Cl, Br, I and are therefore assigned to (B 12) -X stretching and (B 12) -X bending modes, respectively.
