Substituted cobaltocenes (RC5H4)2Co (R = Me, Z-Pr, and n-Bu) have been intercalated into the layered dichalcogenides TaS2 and ZrS2 by direct reaction of toluene solutions of the organometallic compounds and the solid disulfides. Intercalates of TaS2 have also been prepared by ion exchange of the hydrated sodium intercalate with organometallic cations in aqueous solution. Lattice expansions of the host disulfides on intercalation have been determined by powder X-ray diffraction and are discussed in relation to the orientation of the organometallic cation between the layers. Some chemical reactions of the intercalates and some ion-exchange experiments in nonaqueous solvents are described.
