Crystallization induced chiral locking of a central labile core in a star-shaped tetra-nuclear complex†
Abstract
The central labile Al(III) core of a star-shaped tetra-nuclear metal complex, [{Δ-Ru(III)(acac)2(taet)}3Al(III)] (acac = acetylacetonato; taet = tetraacetylethanato), which was synthesized by reacting Δ-[Ru(III)(acac)2(taetH)] (taetH = singly protonated taet) with an Al(III) ion in solution, was found to be locked as a Λ-form in the solid state.
