 Title    R obert Schlögl and H anns  
 Abstract    Intercalation compounds of graphite with SnCl4 have been prepared by reaction in SOCl2/CCl4 or by UV irradiation in CC14 or 1,2-dichloroethane. Mix­ tures of 1st, 2nd, and 3rd stages have been obtained. Chemical analyses and 119Sn Mößbauer spectra indi­ cate that SnCle2^ ions are intercalated. Solvent molecules are co-intercalated.

 Title    Klaus-Jürgen Range* and H elm ut  
 Abstract    The unit cell of N aN iA s04 is rhombohedral, space group R 3, with a — 4.955(5) Ä, c = 26.47(3) Ä and Z = 6. The crystal structure com­ prises three-layer units consisting of one "octahe­ dral" layer, built up from NiO^-octahedra, and two "tetrahedral" layers, built up from A s0 4-tetrahe-dra. Sodium ions are situated between these layers, having a distorted (4+3) coordination.

 Title    Form ation of D iphosphate from Am idophosphoric Acid in Aqueous Solution  
 Abstract    A nearly saturated solution of amidophosphoric acid in water hydrolyses to yield diammonium diphosphate. This reaction provides a diphosphate synthesis in water starting with a solution of N-methylcarbamoylphosphate which is readily ob­ tained through the action of methylisocyanate upon the aqueous solution of a hydrogenphosphate.

 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°.

 Title    Spaltung von S4N4 zu S2N2 bei Raumtemperatur: Darstellung und Struktur von S2N2 * 2AlBr3 Cleavage of S4N4 to S2N2 at Room Tem perature: Preparation and Structure of S2N2 * 2A lB r3  
 Abstract    The compound S2N2 • 2A lBr3 has been prepared by reaction of S4N4 with AlBr3 in 1,2-di-bromoethane at room temperature. Its crystal and molecular structure have been determined by X-ray diffraction; R = 0.068. Crystal data: monoclinic, P 2Jn, a = 9.594(5), b = 9.975(4), c = 7.528(4) Ä , ß = 111.36(5)°. The S2N2 ring of the centrosymmetrical complex is bonded via its nitrogen atoms to two AlBr3 units thus completing coordination tetrahedra around the A1 atoms. Bond distances and angles within the S2N2 ring are d(S—N) = 1.629(13) and 1.651(13) Ä , < (S —N -S) = 95.8, and < (N —S—N) — 84.2°. Whereas the S—N bond lengths agree closely with those of free S2N2, the angle at N is enlarged by ca. 5° and the angle at S is decreased by ca. 5°. The sulfur atoms form two close S --B r contacts of length 3.149 (intramolecular) and 3.193 (inter-molecular) Ä , respectively. The intermolecular attractive nonbonded S - • -Br interactions tie the complexes together in a way that leads to infinite chains which run parallel to the crystallographic z axis.

 Title    Impedance of an Oxygen Reducing Gas-Diffusion Electrode  
 Abstract    The impedance of teflon bonded electrodes was measured in the frequency domain. These electrodes based on activated carbon as electrocatalyst were developed for fuel cell applications. When feeding the electrode with air or oxygen the impedance spectra could be explained by two Nernst diffusion processes and a small charge transfer process. Two methods for separating the measured impedance into partial impedances related to differ­ ent steps of the electrode reaction are presented. A least square fit procedure is described which has been applied successfully to the impedance analysis of porous electrodes.

 Title    Reaktionen von Metallkomplexen mit kleinen Ringen, XI [1] Ringöffnung von Aziridinen mit Metallcarbonylhydriden; /J-Aminoacylchelat-Komplexe von Mangan, Molybdän, Wolfram und Cobalt Reactions of Metal Complexes with Small Rings, XI [1] Ring Opening of Aziridines by Metal Carbonyl Hydrides; /?-Aminoacyl Chelate Complexes of Manganese, Molybdenum, Tungsten and Cobalt  
 Abstract    Ring Opening of Aziridines, /3-Aminoacyl Complexes of Manganese, Cobalt, Molybdenum, Tungsten The metal carbonyl hydrides HM (CO)3(jr-C5H5) (M = Mo, W), HMn(CO)4L, HCo(CO)3L (L — CO, PPh3) react with aziridines by protonation of aziridine, nucleophilic attack of the corresponding carbonyl metallate and CO insertion to give the /?-aminoacyl complexes 2—7. The ring opening of C-substituted aziridines is regiospecific. With alkyl substituted aziridines the nucleophilic attack of the carbonyl metallate occurs at the sterically less hindered carbon atom, with phenyl substituted aziridines at the phenyl substituted carbon atoms. From the reactions of HM(CO)3(jr-C5H5) with optically active aziridines, which afford complexes with an asymmetric metal atom, only one diastereomer could be observed. The mechanism of these reactions is discussed and the spectral data (IR, 'H NMR, MS) of the complexes are reported. /3-Aminoacyl complexes have also been obtained by addition of amines to [(jr-C5H5)(CO)3M(alkene)]+BF4_ (M = Mo, W). The methyl complex H3CMn(CO)5 reacts with aziridine to give the acetyl complexes H3C C (0)M n (C 0)4(aziridine) and H3C C (0)M n (C 0)3(aziridine)2, respectively.

 Abstract    Three compounds of the type Ti[MB(CN)6] (MB = Co, Rh, and Ir) have been synthesized and characterized by means of their X-ray diffraction powder patterns, magnetic measurements, infrared, electronic, and X-ray photoelectron spectra. All compounds crystallize in the face-centered cubic system and form a three-dimensional framework of two octahedral coordination units MBC6 and TiN6. Upon the formation of Ti[MB(CN)6] from the corresponding potassium salt, the jz back-donation in the [MD(CN)6]3-moiety is enhanced by the bridge formation through the cyanide ligand.

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.
