Hypercoordination (hypervalency) of some organo-silicon or -germanium compounds has attracted considerable attention. We were interested in hypercoordinated triarylgermane (1a) in which NMe<SUB>2</SUB> group is the ligand. We prepared some analogs of la with a <I>t</I>-BuO (1b) or MeS (1c) group as the ligand in which the germanium atom was found hypercoordinated. We also prepared a series of derivatives of OMe (4a) species in which such substituents as halogen (4b-4d), Me (4e) or Ph (4f) were introduced. All compounds except 4f were found hypercoordinated though the structure varies depending on the nature of the substituent on germanium. A novel group of hypercoordinated organogermanium compounds was also prepared and their structure was elucidated. The dynamic behavior of these was explained in terms of pseudorotation. A method to prove the existence of hypercoordination of germanium atom was proposed based on the halfwidth of <SUP>73</SUP>Ge NMR resonances.
