Ti Content

A series of CrTiN films were successfully deposited by medium frequency magnetron sputtering in a mixture gas of nitrogen and argon. X-ray diffraction analysis shows that the CrTiN have preferential orientation of (200). The films show low friction and low wear rate at a certain percentage of the Ti content.

The CrN films and CrBN films were successfully deposited by medium frequency magnetron sputtering in a mixture gas of nitrogen and argon. X-ray diffraction analysis shows that the CrN have preferential orientation of (111), (200) and (222). And the patterns of CrBN films is similar to that of CrN. The CrN films have smooth surfaces with dense and continuous microstructure and the CrBN films have glassy packed structure without columnar grains. The hardness of CrBN films were remarkable improved because of B attending.

Boiling Toluene

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.
