资源简介:
The species [(HC(PPh2NSiMe3)2Cr(μ-Cl)2] was prepared and structurally characterized. It is shown to exist in two structural isomers: one in which the Cr center adopts a pseudo-square-planar coordination geometry and another where the metal coordination sphere is better described as trigonal bipyramidal. Preliminary assessment of the catalytic activity in ethylene polymerization is also reported.
