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 MgF2 frameworks are present in the title compounds obtained from the reaction of [Cp*TiF3] (Cp  C5Me5) with elemental sodium and magnesium, respectively. In these reactions TiIV is reduced to TiIII. The Cp*Ti units function as organometallics shields around the cagelike core and are responsible for the high solubility of the compounds.
