Monocyclopentadieny1titanium(III) compounds. III. Complexes of oxygencontaining ligands

Abstract

Complexes of the type cpTiX₂,nL [where cp = π-cyclopentadienyl; X = Cl or Br; n = 1 when L = 1,2-dimethoxyethane (dme); n = 2 when L = ethanol (EtOH), or methanol (MeOH)] have been prepared. Various physical properties, including magnetism and electronic spectra, have been measured and interpreted on the basis of six-coordinate titanium(III) atoms. The magnetic moments of all complexes approximate to the spin-only value.     Reactions with dioxan did not result in the formation of stoichiometric complexes, while β-diketones caused rupture of the cp-Ti bonds as well as the halide-titanium bonds giving known tris-β- diketonates of titanium(III).
