Molecular Solids as Ligands in Organometallic Chemistry: [CpTi₆Na₇F₁₉·2.5thf] (Cp^* C₅Me₅) and [CpTi₄Mg₂F₁₂·7thf], Links Between Ionic Solids and Organometallic Compounds

Abstract

Central NaF and MgF 2 frameworks are present in the title compounds obtained from the reaction of [Cp * TiF 3 ] (Cp  C 5 Me 5 ) with elemental sodium and magnesium, respectively. In these reactions Ti IV is reduced to Ti III . The Cp * Ti units function as organometallics shields around the cagelike core and are responsible for the high solubility of the compounds.
