 Title    Uber die Reaktionen von Molekülen  
 Abstract    (R2CS)2 (R = CF3, CI) und C12CS mit XeF+MF6-(M = As, Sb) und Kristallstruktur von (CF3)2CSC(CF3)2SF+SbF6-[1] O n th e R eactions of M olecules (R 2C S)2 (R = C F 3, Cl) and C12CS with X eF +M F6_ (M = As, Sb) and C rystal Structure of (C F3)2C SC (C F3)2SF+SbF6~ [1] R olf M inkwitz XeF+MF6_ (M = As, Sb) reacts with ((CF3)2CS)2 and C12CS to form the corresponding monofluorinated sulfonium hexafluorometalates. The salts have been characterized by vibra­ tional and 19F NMR spectroscopic measurements. (CF3)2CSC(CF3)2SF+SbF6^ crystallizes in the monoclinic space group C2/c with a =o 14.791(10), b = 11.093(6), c -10.356(6)Ä, ß -119.83° and Z = 4. With a value of 1.51(1) A d (S -F) is comparable to the SF-bond distance in (CF3)(C1)CSC(CF3)(C1)SF+AsF6-.

The ligand behaves as a bidentate donor towards nickel(II) as shown by the formation and X-ray analysis of the complex {PPO(H)}NiBr2 (4). In the square planar complex 4 only the PPh2 groups are coordinated. In the tetrahedral complex [{PPO(H)}2Ni](BF4)2 (5) two PPO(H) ligands sur­ round nickel as bidentate ligands.

 Abstract    Single crystals of Cd() 73Cu<,.27V 20 6 were prepared by solid state reactions. X-ray investiga­ tions lead to monoclinic symmetry, space group C \h-C2lm , a = 9.339, b = 3.5604, c = 6.893 A , ß = 111.85°, Z = 2. It belongs to the Brannerite structure, showing a statistical distribution of Cd2+ and Cu2+ on one point position. The crystal structure of Brannerites is discussed with respect to the distorted O 2-octahedra around V 5+ and the influence of the Jahn-Teller active Cu-+ ion to the shortened M2+Oa octahedra.

 Abstract    D ialane(4), Insertion of Te Tetrakis[bis(trimethylsilyl)methyl]dialane(4) 1 with an A l-A l bond and Et3P+-T e " give under mild conditions the title com pound R2A 1 -T e -A 1 R 2 (R = CH(SiM e3)2) 2 in high yields. D ue to the high steric shielding 2 is m onom eric even in the solid state with an angled A l -T e -A l group (110.4°) and an A l-T e bond length o f 254.9 pm as expected for a A l-T e single bond with the atoms in low coordination numbers. A hindered rotation of the bulky substituents is observed in solution probably caused by steric restrictions similar that in ana­ logous compounds with A l -S -A l or A 1 -C H 2-A 1 groups.

The thermal decomposition of the former com plexes yields the metal oxides while the latter mixed metal complexes give the corresponding metal cobaltites as the final residue. Formation of metal cobaltites has been confirmed by TG weight loss, IR spectra and X-ray diffraction.

 Abstract    Various dialdehydes (1 -5) were formed by addition of dithiols to acrolein. Reaction of these dialdehydes with N-alkylhydroxylamines afforded dinitrones the two nitrone groups of which were joined by an alkylidene chain containing two sulfur atoms (6 a ,b -1 0 a ,b). Cycloaddition of these dinitrones with dimethyl acetylenedicarboxylate proceeded in the usual way giving bis(4-isoxazolines) (lla -1 5 a) .

 Title    Tinorganic Fluorides Function as Fluorinating Reagents for Chlorides of Main Group Elements - Quantitative Recycling of the Fluorinating Reagent  
 Abstract    Fluorine-Chlorine Exchange, Main Group Compounds PF3 is obtained in high purity by reacting PC13 with Me3SnF. Alternative fluorinating reagents for this reaction are Ph3SnF and (/-C4H9)3SnF. The reaction with the isobutyl derivative is less complicated since the resulting chloride is a liquid in contrast to Ph3SnCl being a solid. PC15, MeCOCl, SiCl4, Me3SiCl, and SOCl2 react with Me3SnF to give also the corresponding fluorides. The resulting chlorides are easily converted again to the fluorides. A quantitative recycling o f the fluorinating reagent is therefore achieved.

 Title    Cu6Br6(NPM e3)4, a Mixed-Valent Cluster of Copper  
 Abstract    Cu6Br6(N PM e3)4 has been prepared as a by-product from the reaction o f CuBr with M e3SiNPM e3 in a C H 2C12 suspension. The dark red-violet crystals, which contain three molecules CH2C12 per unit cell, have been characterized by a crystal structure determination. Cu6Br6(N PM e3)4 -3 C H 2Cl2: Space group P I, Z = 2, lattice dim ensions at -9 5 °C: a = 1165.2(4), b = 1168.9(4), c = 1842.9(6) pm, a = 75.61(3)°, ß = 84.15(3)°, y = 61.08(2)°, 6918 observed unique re­ flections, R = 0.066. In the cluster molecule Cu6Br6(N PM e3)4 the copper atoms form a nearly ideal octahedron with C u -C u bond lengths of 268.8 pm in average. Each of the Cu atoms is con­ nected with a terminal bromine atom. Four planes of the octahedron are capped by ^ -n itrogen atoms o f the (N P M e3) _ groups.
