Hypervalence in germanium compounds containing the tetracylic moiety {S(C6H3S)2O}Ge via O---Ge transannular interactions: A structural study. Benito Flores Chávez, José G.

Abstract
The synthesis of [{S(C6H3S)2O}GeRnHal2?n] compounds (R = Et, Ph; Hal = Cl, Br; n = 20) is described. The acidity of the GeRHal2+ fragment enhances a transannular OGe interaction, prompting a trigonal bipyramidal germanium local geometry; the GeR22+ less acid fragment present has an opposite effect.
