The reaction of triphenylcyclopentadienyl potassium with praseodymium and erbium chloride tetrahydrofuranates gives, depending on the reactant ratio, tetranuclear ate complexes, [{(Ph3C5H2)-Pr(THF)}2(µ2-Cl)2(µ3-Cl)3K]2(C7H8)4 (I) and [{(Ph3C5H2)Er(THF)}2(µ2-Cl)2(µ3-Cl)3K(THF)]2 (III), or binuclear ate complexes [(Ph3C5H2)2LnCl(KCl)]2 Ln = Pr (II), Er (IV) (CCDC nos. 2224244 (I), 2224243 (II), 2224245 (III), 2224242 (IV)). The structurally similar complexes I and III are based on the {[Ln2(µ-Cl)3]2(µ-Cl)2K2} core, and in III, the potassium cation is additionally coordinated to the THF molecule. The isostructural complexes II and IV have the binuclear [Ln(µ-Cl)2K]2 core.
