 Title    Neuartige basische Liganden für die homogenkatalytische Methanolcarbonylierung, XXI [1] Synthese und Eigenschaften von (Ether-Phosphan)-Platin-Komplexen Novel Basic Ligands for the Homogenous Catalytic Methanol Carbonylation, XXI [1] Synthesis and Properties of (Ether-Phosphane) Platinum Complexes  
 Abstract    The (ether-phosphane) complexes m -C l2Pt(Ph: P ~ D)2 (2a, b) [D = C H 2C4H 70 (a). C H 2C4H 70 2 (b)] are obtained by reaction of Ph2P ~ D (la , b) with either K2PtCl4 or Cl2Pt(CO D) (C O D = 1,5-cyclooctadiene). Both Cl ^anions are abstracted from 2a, b using A gSbF(1 to give the cationic bischelate complexes [Pt(Ph2P D)2][SbFh]2 (5a, b). The stepwise cleavage and reform a­ tion of Pt —O bonds in (ether-phosphane) platinum complexes is dem onstrated bv the sequence 5a —> [rä -(P h 2P D)(Ph2P ~D)P tC l][S bF 6] (6 a) -* [rra«5-(Ph2P ~ D)2PtC O (C l)][SbF6] (7 a) -* 5a, when 5a, 6 a, and 7a are reacted with KC1. CO, and AgSbF,,, respectively. Reduction of 2a with N aB H 4 results in the form ation of rra/2s-H 2Pt(Ph2P ~ D)2 (4a). In the presence of HC1 2a js re­ formed. Excess N aBH 4 or heating of 4a yields the bischelate platinum(O) complex Pt(P h: P D)2 (3a), which is also jso lated by reduction of 2a with sodium amalgam. A general method for obtaining P t(P h2P D)2 (3 a —c) [D = C H 2C H 2O C H , (c)] is the substitution of C O D in P t(C O D)2 by the ether-phosphanes l a —c. The structures and bonding properties of the com pounds 2 —7 are discussed on the basis of their 31P {1H } NMR and IR spectra.

 Title    Die Wechselwirkung von N 3F mit Lewis-Säuren und HF. N 3F als möglicher Vorläufer für die Synthese von N 3+-Salzen The Interaction of N 3F with Lewis-Acids and HF. N 3F as Possible Precursor for the Synthesis of N 3+ Salts  
 Abstract    Triazadienyl fluoride, N 3F, forms stable adducts with BF3 and AsF5 at low temperatures, as demonstrated by infrared measurements. The Lewis acids are bonded to the Na-atom of N 3F, as deduced from the data for 15N-isotopically enriched N 3F. The basicity of N 3F is comparable to that of ethine and ethene, according to the HF stretching frequency of the N 3F/HF complex isolated in an argon matrix. Despite the low NF bond energy (<150 kJ/mol), abstraction of the fluoride ion and formation of an N 3+ salt was not possible. The different behavior of N 3F and C1N3 towards Lewis acids is discussed.

 Abstract    The structural parameters and IR frequencies of the following anionic fulminate complexes were computed at the density functional BPW91 level of theory using a 6-31++G(2d) basis for C, N, O, Co, Ni, and Zn and quasi-relativistic ECP60MWB core potentials for Pt, Au and Hg: [Co(CNO)6]3-(Oh), [Ni(CNO)4]2-(D 4h), [Zn(CNO)4]2-(Td), [Pt(C N 04]2-(D 4h), [Au(CNO)2]~ (£>xh) and [Hg(CNO)4]2-(Td). The structures were optimised within the symmetries stated above and were found to represent true minima (number of imaginary frequencies, NIMAG = 0). The agreement between the calcu­ lated structural parameters and characteristic asymmetric and symmetric CNO stretching fre­ quencies is very good for all complexes.

 Title    The Structure of Zinc Chloride Complexes in Aqueous Solution  
 Abstract    The structure of zinc chloride complexes with different ratios of chloride to zinc, formed in concentrated ZnCl 2 aqueous solutions, were determined from large-angle X-ray scattering using concentrations of the chloride complexes estimated by complementary Raman spectroscopic mea-surements. The highest chloro complex, [ZnCl 4 ] 2 ~, is tetrahedral with a Zn-Cl bond length of 2.294(4) Ä. The trichloro complex, [ZnCl 3 ]~, which coordinates one water molecule, is pyramidal with the Cl-Zn-Cl angle 111°. The Zn-Cl and the Zn-H 2 0 bonds are 2.282(4) and 1.9 A, respec-tively. The two lower complexes, [ZnCl 2 ] and [ZnCl] + , cannot be separated by Raman spectra. o The average Zn-Cl distance in these complexes is 2.24 Ä, and the average Zn-H 2 Ö distance is 1.9 A. In [Zn(H 2 0) 6 ] 2+ the Zn-H 2 0 distance is 2.15 Ä. of zinc (II) chloride complexes; structure of hydrated non-complexed zinc (II) ion.

 Title    Darstellung und spektroskopische Charakterisierung von Tetrahalogenooxalato-Osmaten(IY)  
 Abstract    Reaction of [OsXe] 2-(X = CI, Br, I) with oxalic acid in water gives the very stable and deeply coloured new complexes [OsX40x] 2-which can be precipitated as alkali or tetra-alkylammonium salts. The salts with long-chain alkylammonium ions are soluble in all common no polar solvents. The IR and Ra spectra and the depolarization ratios are consistent with the local C2v-symmetry. The coupling between the vibrations of co-ordinated oxalate and with the skeletal [OsX402]-modes is apparently small. The optical spectra have been studied at low temperature (10 K). Analogous to [OsXe] 2-the very intense absorptions in the UV and VIS are assigned to the electric dipole allowed electron transfer from "(jr+cr)tiu, 7rt2U(y7), 7it2u(y8) and (<r-f-7r)tiu" to "dt2g". By the descent in symmetry each of these transitions is further split in three components (Ai, Bi, B2) corresponding to the three different groups of ligands, X2 tr -, X2 C -and ox. The distinction between the X2 tr --*-Os and X2 C --> Os is caused by a static trans-effect and depends on the difference of the optical electronegativities induced by ox. This splitting is not observed for [OsCLiox] 2 -but is about 900 cm-* for [OsBr4ox] 2 -and 1200 cm" 1 for [OsI4ox] 2 -. The well defined bands in the NIR and VIS are assigned to the intraconfigurational d-d-transitions between the spin-orbit components in the octahedral doublegroup Oh* splitted by the lower C2v-symmetry. Some of the zero-phonon transitions within the split of the 3 Tig, Oh-groundstate exhibit extremely high intensities (e~2500 cm 2 /mmol). The assign-ment of these transitions is improved by the electronic Ra spectra. The finestructure of some of the d-d-transitions originates from coupling with Ai vibrational modes especially with Vs(C-O).

 Title    The Metal Complexes of Heterocyclic /?-Diketones and their Derivatives, Part VIII Synthesis, Structure, Proton NMR and Infrared Spectral Studies of the Complexes-Phenyl-3-methyl-4-trifluoroacetyl-pyrazolone-5 (HPMTFP)  
 Abstract    of Al(in), Fe(ffl), Co(ffl), Rh(m), In(ffl), and Zr(IV) with l New complexes of Al(III), Fe(III), Co(III), Rh(III), In(III) and Zr(IV) with 1-phenyl-3-methyl-4-trifluoroacetyl-pyrazolone-5, (HPMTFP), have been synthesized and charac-terized by means of elemental analyses, conductivity and magnetic moment measurements, proton NMR and infrared spectroscopy. It is concluded that the ligand, HPMTFP, reacts as a bidentate enol forming neutral metal chelates. The PMR spectra of chelates suffi-ciently soluble in deuterated NMR solvents were recorded and studied. The IR spectra are measured between 4000-200 cm -1 and assignments are proposed for the observed fre-quencies. The M-0 stretching frequency follows the order: AI > Rh > Fe — Co = Zr > In.

 Title    P(C6H5)4[VOBr4]: Synthese, IR-Spektrum und Kristallstruktur P(C6H5)4[VOBr4]: Synthesis, IR Spectrum and Crystal Structure  
 Abstract    PPh 4 [VOBr4] was prepared by the reaction of PPh4Br with VOBr3 in CH2Br2 solu-tion. The structure of the dark violet crystals was determined with X-ray diffraction. PPli4[VOBr4] crystallizes in the space group P4/n with the lattice constants a = 1275.9 and c = 784.5 pm with two formula units per unit cell. The structure type corresponds to the frequently encountered AsPh4[RuNCl4] type. The VOBr4~ ion forms a square pyramid; the V = O bond has a length of 155 pm. In the IR spectrum, the V —O stretching vibration appears at 922 cm -1 .
