Scandium complexes were isolated as THF-free compounds with a pseudo five-coordinate environment, while yttrium and lutetium complexes were isolated with an octahedral geometry due to the coordination of a THF molecule. The fluxionality of complexes 1–12 in solution was investigated by VT NMR spectroscopy. The structures of these compounds were determined by spectroscopic
