A Molecular Heterometal Amide with High Molecular Dynamics: Does the Lithium Atom Orbit?

Temperature-dependent NMR spectroscopy allows the movements of substituents and groups in [Me2Si(NSiMe3)2]2InLi to be followed. These movements finally result in a process in which the lithium atom also migrates with respect to the other heavy atoms. In one of the models the result is a quasi-orbital movement of the lithium atom around the core of the molecule occupied by an indium atom (picture shown on the right).
