X-ray analysis of the complex [2,2‘-S-(4,6-tBu2C6H2O)2]2Ge reveals a hexacoordinated Ge atom with bonding of the transannular sulfur atoms in the eight-membered rings to germanium. An octahedral geometry about Ge is observed. 1H NMR spectral data are consistent with the hexacoordinate structure being maintained in solution. This six-coordinate Ge complex provides a model for the possible bonding and structure of TS's and intermediates in nucleophilic substitution reactions at Ge.
