The preparation and characterization of acetylacetonato-bis(η-methylcyclopentadienyl)titanium(IV) complexes

Summary A series of [L₂TiL]⁺X^–compounds where L is the conjugate base of acetylacetone, L=-MeC₅H₄ and X^–= ClO₄^–, BF₄^–, FeCl₄^–, ZnCl₃(H₂O)^–, SnCl₃^–, CdCl₄^2–, HgCl₄^2–, Br^– or I^–, have been prepared by adding X^– to the aqueous solution of [L₂TiL]⁺Cl^–. Conductivity measurements in nitrobenzene for all compounds indicate that these complexes are electrolytes. The i.r. frequencies for various vibrational modes have been assigned. The ligand L appears to be chelating and the titanium atom is essentially tetracoordinate. The bonding in these complexes is discussed.On study leave from S. D. College, Muzaffar Nagar, U.P., India.
