Abstract

Chiral [(salen)Li₂·hmpa]₂ has a Li ₄O₄ cubane-type core in the solid but low-temperature NMR spectroscopy reveals a racemisation equilibrium in solution; deliberate addition of H₂O to [(salen)Li₂]_n in the presence of tmen produces a species having two Li₄O₄ cubes sharing a common oxygen and containing tmen ligands acting in a hitherto unobserved monofunctional mode.
