 Title    Komplexchemie polyfunktioneller Liganden, XXXVIII  
 Abstract    Präparative und schwingungsspektroskopische Untersuchungen zum Reaktionsverhalten von Mn2(CO)10 gegenüber dem tritertiären Phosphin l.l.l-Tris(diphenylphosphinomethyl)äthan Complex Chemistry of Polyfunctional Ligands, XXXVIII 1 Preparative and Vibrational Spectroscopic Studies of the Reaction of Mn2(CO)10 with the Tritertiary Phosphine 1,1 ,l-Tris(diphenylphosphinomethyl)ethane Decacarbonyldimanganese reacts with the tritertiary phosphine l,l,l-tris(diphenylphos-phinomethyl)ethane (triphos) to give the ionic complex [Mn(CO)3triphos][Mn(CO)5]. Treatment of [Mn(CO)3triphos][Mn(CO)5] with Na[B(C6H5)4], HC104 and NH4PF6 yields the manganese (I) salts [Mn(CO)3triphos]Y (Y = B(C6H5)4, C104, PFe). The IR (2100-300 cm -1) and FIR spectra (350-200 cm -1) of all compounds are reported. Based on Ra-man polarization data the assignment of the v(CO) (Ai + E), <5(MnCO) (Ai + 2 E), j>(MnC) (Ai + E) and v(MnP) (Ai) modes was possible for the coordination polyhedra cts-Mn(CO)3P3 (point group C3v). The i'(MnP) (E) mode was unobserved due to its very low frequency.

 Title    Darstellung und Reaktionen der Oxovanadin(V)-tricarboxylate Synthesis and Reactions of Oxovanadium(V) Tricarboxylates  
 Abstract    Monomeric oxovanadium(V) tricarboxylates VO(RCOO)3 are prepared by reaction of VOCI3 with an excess of silver carboxylate in CH2CI2 or by depolymerization of (V02RC00)n in carboxylic acid anhydride. Their properties are studied by IR and X H NMR spectroscopy as well as by chemical reactions such as thermolysis, solvolysis, redistribution and complex formation. The structure of 2,2'-dipyridyl and 1,10-phenanthroline complexes [VO(RCOO)3 • B] (B = C10H8N2, C12H8N2) has been found to be octahedral with meridional arrangement of the carboxylate ligands. Syntheses of Na[VO(CH3COO)4] and Ba[V02(CH3C00)3] • 2CH3COOH are described.

 Title    Darstellung und Charakterisierung von Tetrabutylammonium-Tetraiodooxotechnetat(V), (TBA) [TcOI4] Preparation and Characterization of Tetrabutylammonium Tetraiodooxotechnetate(V), (TBA)[TcOI4]  
 Abstract    Pure (TBA)[TcOIi] is prepared from (TBA)[TcOCl4] by ligand exchange reaction with Nal in acetone. The vibrational spectra indicate C4v symmetry for the complex ion. On excitation with the 514.5 nm line of an Ar-laser a resonance Raman spectrum is obtained showing v(TcO) = 996 cm -1 and four of its overtones, symmetrically surrounded by groups of bands arising as well from the sums as from the differences of frequencies with the other fundamentals. In contrast to the ligand exchange reaction the reduction of Tc04 _ with conc. HI yields products always contaminated with polyiodides. The extremely strong Raman scatterer (TBA)l3 is detected by a characteristic doublet at 111 and 116 cm -1 and even small amounts of it cover the Raman spectrum of (TBA)[TcOI4].

 Abstract    (Benzoyloxy)-and (pentafluorobenzoyloxy)diphenylphosphanes RC(0)0PPh2 (2a, b) [R = C6H5 (a), C6F5 (b)] can be obtained by reaction of ClPPh2 (1) with Na02CC6H5 and Ag02CCeF5, respectively [eq. (1)]. Oxidation of 2a with molecular oxygen yields (benzoyl-oxy)diphenylphosphane oxide (3a) [eq. (2)]. The complexes (0C)5CrPPh20C(0)R (oa, b) are formed by the action of Na2OCC6Hs and Ag02CC6Fs, respectively on (OC)5CrPPh2Cl (4) [eq. (3)]. The chemical and spectroscopical properties of the (aroyloxy)diphenylphosphanes (2 a, b) are compared with the corresponding aryldiphenylphosphane oxides.

 Title    Eine neue Synthese, das Schwingungsspektrum und die Kristallstruktur von Tetraphenylarsonium-hydrogendichlorid As(C6H5)4 [C12H] A New Synthesis, the Vibrational Spectrum and the Crystal Structure of Tetraphenylarsonium Hydrogendichloride AsfCeHsMC^H]  
 Abstract    As(C6H 5)4 + [Cl2H]-crystallizes in the monoclinic space group B2/b with four formula units per unit cell, the lattice constants being a— 1704, 6= 1751, c — 705 pm and y = 92.73°. The crystal structure was determined and refined from X-ray diffraction data to a residual index of R = 0.043. The CI2H-ion is situated on an inversion center with a C1---C1 distance of 309 pm. The IR and Raman spectra confirm the presence of sym-metrical CI2H -ions; the observed splitting of IR bands can be explained by factor group analysis. A simple procedure for the preparation consists of the reaction of HCl with As(C6H 5)4Cl.

 Title    Darstellung und spektroskopische Charakterisierung von Tetrachloro-und Tetrabromo-Oxalatoiridaten(IV) Preparation and Spectroscopical Characterization of Tetrachloro-and Tetrabromoiridates(IV)  
 Abstract    On treatment of [IrXß] 2-with oxalate in aqueous solution at first [IrX40x] 3-(X = Cl, Br) is formed, which after extraction with pentylammonium ions into CH2CI0 can be oxidised by X2 to give the corresponding pure Ir(IV) complexes [UXLjox] 2-. The IR and Raman spectra are assigned according to point group C2v-The UV/VIS absorption spectra show strong CT bands of transitions from "(.t + <7)tiu"-and "jrt2U"-ligand niveaus to t2g 5 (Ir IV). These are split into three components by spin-orbit coupling and corresponding to the different groups of ligands: X| r , Xg, ox. The spectrum of (TBA)2[IrBr40x] recorded at 10 K is highly resolved, showing a splitting of the Br£ r ->Ir(IV) and Bg -n>-Ir(IV) transi-tions by 1000-1400 cm -1 . In the NIR-region two d-d-transitions are observed super-imposed with a fine structure by coupling with vibration modes.

 Title    Darstellung und spektroskopische Charakterisierung von Hexachloroosmat(V)  
 Abstract    (TEA)[OSC16] is formed quantitatively by heating solid £RARAS-(TEA)[OsX4(CO)2] (X = Br, I) in a stream of chlorine at 120 °C, and can be purified by recrystallisation from CH2CI2 without decomposition. It is reduced immediately by acetone, methanol, CU, Br~, I -to give [OsCl6] 2 -. The standard potential [OsCl6] -/[OsCl6] 2 ~ in acetonitrile referred to the saturated mercury-mercurous sulphate electrode is 0.840 V. The IR and Ra bands of (TEA)[OsCl6], assigned according to point group Oh, are shifted to higher frequencies compared with (TEA)2[OsCle]. The excitation at 488.0 nm gives a resonance Raman spectrum exhibiting 6 overtones of vi and combination tones up to 4 J»I + v-0. The electronic absorption spectrum shows five spin-forbidden intraconfigurational transitions coupled with odd vibrational modes in the near infrared region. The spin-allowed 4 A2g -> 4 T2g, 4 Tig-transitions are observed at 347 and 305 nm. The excited levels can be fitted with the parameters A = 28500 cm-1 , B = 340 cm-1 , $ = 2500 cm 4 , allowing to calculate the nephel-auxetic ratio /J55 to 0.47. In the visible region extensive charge transfer transitions are observed. Based on the strong oxidizing character of Os(V) there is a bathochromic shift of corresponding bands of [OsClß]-in relation to [OsC^] 2-of about 6600 cm -1 and to the isoelectronic [ReCle] 2-of about 13700 cm -1 , respectively. From Jitiu->dt2g the optical electronegativity is calculated to a0pt(Os v) — 2.49.

 Title    Thermoanalytische, IR-spektroskopische und quantenchemische Untersuchungen an Kristallmodifikationen des Trichlorphons Thermo-analytical, IR-spectroscopical and Quantum-chemical Investigations on Crystal Modifications of Trichlorphone  
 Abstract    Several modifications of trichlorphone can be prepared by recrystallizing the raw substance from various solvents under special conditions. One of these modifications is obviously an optical isomer. The different thermo-analytical behavior of the modifications is probably due to the relative content of distinct dimer species. This interpretation is supported by quantum-chemical calculations and by analysis of infrared spectra. Die phosphor-organische Verbindung 2.2.2-Tri-chlor-1 -hydroxyethyl-dimethyl-phosphonat (Tri-chlorphon, Metrifonat) ist ein seit etwa 30 Jahren bekanntes Insektizid [1], das auch als Arzneimittel für die Behandlung von Schistosomiasis eingesetzt wird [2]. Diese im folgenden als Trichlorphon be-zeichnete Substanz hat nach Schräder [3] einen Schmelzpunkt von 356-357 K. In den meisten Fäl-len hegen jedoch die von verschiedenen Autoren angegebenen Schmelzpunkte um 348-351 K. Bei der Reinigung von Trichlorphonproben durch Umkristallisieren stellten wir fest, daß man je nach den gewählten Bedingungen mehrere Kristallfor-men erhält, deren Schmelzpunkte zwischen 343 und 383 K variieren. Über die Erscheinung der Polymorphie beim Tri-chlorphon sind uns aus der Literatur keine Hinweise bekannt. Das Ziel unserer Untersuchungen war es deshalb, mit Hilfe strukturanalytischer Methoden eine Erklärung für die beobachteten Schmelzpunkts-differenzen zu finden. Von den bisher publizierten physikochemischen Eigenschaften der Substanz sind neben den zahl-reichen Schmelzpunkten hauptsächlich die optische Aktivität und die Bimolekularität als Ausgangs-punkt für eine Strukturanalyse von Bedeutung.

 Title    Über das [C7H7Fe2(CO)5]--Anion (C7H7 = Cycloheptatrienyl) About the [C7H7Fe2(CO)5]--Anion (C7H7 = Cycloheptatrienyl)  
 Abstract    The extremely unstable anionic complex [C7H7Fe2(CO)6]~ (C7H7 = cycloheptatrienyl) which decomposes in polar solvents under CO elimination to give [C7H7Fe2(CO)s]~ can be prepared by deprotonation of C7H8Fe2(CO)6 (C7H8 = cycloheptatriene) with NaN(SiMe3)2 in CßHe-The NMR spectra of [C7H7Fe2(CO)5]~ show the highly fluctional character of this anion in solution. The X-ray structural parameters of Ph4As[C7H7Fe2(CO)5] (space group P2i/n) can be interpreted in terms of a rotation of the tub shaped C7H7 ring against the CO bridged Fe2(CO)5 fragment in the solid state. Consequently, each iron atom is alternatingly rj 3 -or ^-coordinated to the allyl anion and the diene part, respectively, of the anionic 8n system of the cycloheptatrienyl ring.
