摘要：

Experimental observations of clusters TeF6 together with molecular dynamics simulations have uncovered some kinetic aspects of phase transitions that can be expected to apply to related systems. It was predicted, accordingly, that under conditions of fast cooling transition-metal hexafluorides could be induced to crystallize into a monoclinic form which had never been observed for the compounds. Electron diffraction studies of large clusters of MoF6 and WF6, generated by condensation of the vapor in supersonic expansions through a Laval nozzle, confirmed the prediction. A rationale for this behavior is advanced.
