Article
Understanding the corrosion susceptibility of Magnox alloys during short- and long-term storage in moist air is important. Corrosion of Magnox AL80, Magnox ZR55 and magnesium has been studied in air containing water partial pressures between 200 vppm and ∼80000 vppm, at temperatures of 46 °C to 96 °C. Specimens were exposed to air, with and without...
Article
The graphite core of Windscale Pile 1 is to be dismantled and packaged for interim storage, together with graphite items, such as dowels and boats from both Pile 1 and 2. These retain substantial amounts of Wigner energy and thus to support their packaging, storage and ultimate disposal, it is necessary to understand the release of the Wigner energ...
Article
The crystal structure of the compound (selenito-O,O′)bis(triphenylphosphine) platinum(II)-benzene() has been determined by a singlecrystal X-ray analysis. The compound crystallizes in the triclinic space group P1̄ with , , ; α = 85.76(1)°, β = 73.39(1)°, γ = 68.52(1)° and z = 2. The structure has been refined to an R value of 0.036 using 4795 obser...
Article
The structural characterization of [Rh2(μ-Cl)(μ-SO2)2(PPh3)4]2(SO4) by single crystal X-ray diffraction techniques has demonstrated that this complex contains two identical square-pyramidal rhodium(I) units linked by a chloro and two sulphur dioxide bridging ligands. The SO2 ligand adopts a novel bridging mode involving dative bonds from rhodium to...
Article
The crystal structures of Rh4(CO)10(PPh3)2 and Rh4(CO)9P(OPh)33 are reported. 31P-1H NMR studies on Rh4(CO)12-x {P(OPh)3}x(X  1, 2 and 3) show that each derivative exists as only one isomer in solution whereas the analogous triphenylphosphine derivatives can exist as different isomers. A quantitative redistribution of triphenylphosphites occurs on...
Article
The synthesis and spectroscopic characterization of the complexes cis-Pt(SR)2(PPh3)2 (R = H. Me, n-Bu and Ph) are reported, together with the single crystal X-ray crystallographic characterization of cis-Pt(SH)2(PPh3)2. The ability of these complexes to act as bidentate ligands towards other metal centres is also briefly described.
Article
The structure of [Rh(η-C5Me5)H(PPh3)2]PF6 has been determined by 1H NMR studies and a single-crystal X-ray analysis. The compound crystallises in the orthrhombic space group P212121 with lattice constants a 12. 926(3), b 15.216-(3) and c = 20.957(4) Å, with Z = 4. The structure was determined using diffractometer data and by least-squares technique...
Article
The crystal and molecular structure oftrans-di(methylsulphito)bis(triphenylphosphine)platinum(II), Pt(SO3Me)2 (PPh3)2, derived from the reaction of Pt(PPh3)2 (O2) with SO2 in MeOH and in the presence of sodium tetraphenylborate(III), has been determined from diffractometer data. The complex crystallizes in the space group P ¯1- (Ci1) with one molec...

In quantitativen Ausbeuten werden aus den Verbindungen (II) und (IV) mit dem Stannylsulfid (I) die Phosphorsulfide (III) und (V) erhalten.
Article
α-P4S4 and β-P4S4 are formed quantitatively by the action of (Me3Sn)2S on α-P4S3I2 and β-P4S3I2 respectively; X-ray crystal structure analysis shows that α-P4S4 possesses D2d molecular symmetry in the crystal.
