Popis: The intercalation of metallocenes (Cp2Co, Cp2Fe, and Cp2Ni, where Cp is η5-C5H5) from the gas phase into the TiSe2 lattice and of cobaltocene from solutions in acetonitrile, carbon tetrachloride, and chloroform into TiSe2 was studied. The insertion of metallocenes from the gas phase into the TiSe2 lattice gives rise to the TiSe2(Cp2M)0.3 compounds (M = Co or Fe) having the same stoichiometry. The reactions with the use of acetonitrile as the solvent for metallocenes, which facilitates the insertion, afford not only the intercalation complex but also the reaction product of metallocene and acetonitrile, viz., (η 5-C5H5)Co(η4-C5H5CH2CN) (1). In the reactions of cobaltocene with chloroform or carbon tetrachloride in the presence of titanium diselenide, only the addition product, viz., (η 5-C5H5)Co(η4-C5H5CCl3) (2), was isolated. The structures of complexes 1 and 2 were studied by X-ray diffraction.
