The [Zr6(μ2-Cl)12Cl6H4]3- ion with C4v Symmetry in the title compounds has been calculated by DV-Xα program. The calculated results show that ther is almost no available covalence bonding between zirconium atoms and significant Zr 4d AO compositions in the MOs. but there are much stronger Zr-Cl(bridging) bonding. All analysis results suggest that these compounds would be the cluster with Zr6Cl12 cage linked by Zr-Cl bridging bonding plus six Cl teminal ligands rather than the hexazirconium cluster in view of the chemical bonding.

The electronic Structure ofCo6(μ_6-C)(μ_3-S)_2(CO)_(12) molecule has been calculated by DV-Xα method. The results show that the reaction mechanism of CS_2 and Co2(CO)8 in synthsis seems only to undergo the additive and decarbonyl processes. The other result worthy of being mentioned is the calculated atonmic charges that are Co0.3+,S1.29+,μ6-Cl. 16-,C0.06- and O0.21-.S atom has not only the positive charge but also four times as much as that of Co atom. This is not in accordance with the electronegativihes of 1.7 and 2.5 respectively for Co and S atom

NMR microscopy has received great attention from various fields of research, especially material science by its possibility to study materials directly without destruction. Although this technique is almost limited to the detection of fluids constricted in solid samples, such as water in biological systems, solvent diffused in a polymer material^1 and liquid saturated rock systems^2, the mechanical defects of high elastic rubbers have also been detected^3 We are extending this technique to the direct study of the effect of y-irradiation on cis 1, 4-polybutadiene (PB). This article deals with the investigation of radiation induced crosslinking of PB by NMR microscopy.
