Reduction of Ti<jats:sup>IV<\/jats:sup>Cp<jats:sub>2<\/jats:sub>Cl<jats:sub>2<\/jats:sub> and ligand exchange led to the formation of [Ti<jats:sup>III<\/jats:sup>Cp<jats:sub>2<\/jats:sub>(NH<jats:sub>3<\/jats:sub>)<jats:sub>2<\/jats:sub>]<jats:sup>+<\/jats:sup>, also obtainable by recrystallization of [CpTi<jats:sup>III<\/jats:sup>Cl]<jats:sub>2<\/jats:sub>. Upon reaction with [K<jats:sub>4<\/jats:sub>Sn<jats:sub>9<\/jats:sub>], ligand exchange leads to [TiCp<jats:sub>2<\/jats:sub>(\u03b7<jats:sup>1<\/jats:sup>\u2010Sn<jats:sub>9<\/jats:sub>)(NH<jats:sub>3<\/jats:sub>)]<jats:sup>3\u2212<\/jats:sup>.

Finally, the large intermetalloid cluster anion [Ti<jats:sub>4<\/jats:sub>Sn<jats:sub>15<\/jats:sub>Cp<jats:sub>5<\/jats:sub>]<jats:sup><jats:italic>n<\/jats:italic>\u2212<\/jats:sup> (<jats:italic>n<\/jats:italic>=4 or 5) was obtained from the reaction of K<jats:sub>12<\/jats:sub>Sn<jats:sub>17<\/jats:sub> and TiCp<jats:sub>2<\/jats:sub>Cl<jats:sub>2<\/jats:sub> in liquid ammonia.
