Intercalation of Metallocenes in the Layered Transition-Metal Dichalcogenides

Abstract

Novel intercalation complexes of many of the layered transition-metal dichalcogenides incorporating the metallocenes of cobalt and chromium have been prepared. Evidence is presented indicating a configuration in which the five-membered rings of the metallocene guest are situated perpendicular to the slabs of the dichalcogenide host. In the complexes the metallocenes apparently behave as pseudo-alkali metals, transferring an electron to the chalcogenide.
