AbstractIn this study, X-ray diffraction analysis is used to investigate the composition of aerosols produced by exploding wires with the current surge from a 4000-joule capacitor. Qualitative analyses of aerosols from 15 different metals exploded in air or inert atmosphere indicate that the particles are crystalline with the normal crystal structure and that explosion of noble metals in air and of base metals in argon produces aerosols consisting of metallic particles. Base metals exploded in air produce aerosols consisting primarily of oxides. Nitrides were not observed. An analytical scheme is described for the Cu-Cu2O-CuO mixtures collected on membrane filters from explosions of copper wires in air. The composition of aerosols is determined for various initial voltages (2-18 kv) on the 20-μf capacitor bank for two series of wires. In one, the weight fraction of CuO increases rapidly with voltage until it accounts for almost the entire sample while the Cu2O and Cu content decrease smoothly. In the other, CuO and Cu2O are about equal for explosions above 6 kv while Cu decreases. Differences are attributed to a change in the circuit and mass of wire used.

Thermolysis of [8,8-(PMe2Ph)2-nido-8,7-PtCB9H11] in boiling toluene solution results in an elimination of the platinum centre and cluster closure to give the ten-vertex closo species [6-(PMe2Ph)-closo-1-CB9H9] in 85% yield as a colourles air stable solid. The product is characterized by NMR spectroscopy and single-crystal X-ray diffraction analysis. Crystals (from hexane-dichloromethane) are monoclinic, space group P21/c, with a = 903.20(9), b = 1 481.86(11), c = 2 320.0(2) pm, β = 97.860(7)° and Z = 8, and the structure has been refined to R(Rw) = 0.045(0.051) for 3 281 observed reflections with Fo > 2.0σ(Fo). The clean high-yield elimination of a metal centre from a polyhedral metallaborane or metallaheteroborane species is very rare.

Dinuclear rhodium(I) η2:η2-cycloocta-1,5-diene (series a) and η2:η2-norborna-2,5-diene (series b) complexes with μ-RCOO- ligands, where R is linear C21H43 (complexes 1a, 1b), CH2CMe3 (2a, 2b), 1-adamantyl (3a, 3b) and benzyl (4a, 4b), have been prepared and characterized by spectroscopic methods. Structures of complexes 2b, 3a and 4a were determined by X-ray diffraction analysis. Complexes prepared show low to moderate catalytic activity in polymerization of phenylacetylene in THF giving high-cis-transoid polymers, but they show only oligomerization activity in dichloromethane.
