Synthesis and Characterization of Some New Metallo-Organic Derivatives of Germanium(IV)

摘要

Compounds of the type GeG_n(OR)_(4-2n) [where G = O(CH2)2S(CH2)O, S(CH2)2O(CH2)2S, S(CH2)2S(CHa)2S; R = Et, Pr~1 and n = 1, 2] have been prepared by the reaction of Ge(OR)4 with 2-hydroxyethyl sulfide, 2-mercaptoethyl ether and 2-mercaptoethyl sulfide in 1:1 and 1:2 molar ratios in refluxing anhydrous benzene. All these complexes are white sticky solid in appearance. After purification and spectral analyses (IR and ~1H and ~(13)C NMR) tetra coordination geometry is proposed around germanium atom.
