(Tris[2-(dimethylamino)phenyl]germyl}lithium (1) has been prepared. The X-ray analysis shows that 1 exists as a monochelated monomer in the solid state, where the lithium atom is coordinated to one of the amino groups and two THF molecules. The interaction between the lithium atom and the amino group induces the distortion of the geometry around the germanium atom. In solution, however, two species exist as evidenced by 1H-, 7Li-, and 13C- NMR spectra. The temperature-dependent behavior of these two species has been analyzed by variable-temperature NMR studies.
