Mononuclear complexes germanium

The redox properties of macrobicyclic iron(II) mono- and binuclear oximehydrazonates and a-dioximates formed by capping with antimony(V) and germanium(IV) triorganyles were studied by cyclic voltammetry [73, 74]. The electrochemical behaviour of these compounds is similar to that of analogous boron- and tin-capped clathrochelates. Oxidation of all mononuclear complexes involves a one-electron process, assigned to the oxidation of encapsulated iron(II) ion to iron(III) ion. This process is electrochemically... 

A number of examples of Zwitterionic five-coordinate germanium(IV) complexes with two dianionic chelating ligands and an alkyl group with a remote basic nitrogen have been isolated reported including mononuclear complexes with 2,3-(HO)2naphthalene or 2-(HO)-carboxylates as the chelate. 

Germanium and tin form stable, diamagnetic /3-diketonato complexes such as M(acac)2 and M(acac)X, where M is Ge, Sn, and X is Cl or I. The M(dike)2 types can be distilled or sublimed they are soluble and mononuclear in benzene and other hydrocarbon solvents.

In this paper, we report on the synthesis and structural characterization of a series of related zwitterionic (molecular) spirocyclic X Si-silicates (mononuclear A, Si-silicon(IV) complexes) containing two bidentate l,2-diolato(2-) ligands derived from a-hydroxycarboxylic acids, such as glycolic acid, 2 methyllactic acid, benzilic acid, and citric acid. In addition, some analogous zwitterionic X Ge-germanates (mononuclear X Ge-germanium(rV) complexes) are described. Furthermore, we report on the synthesis and structural characterization of related zwitterionic x Si,X Si -disilicates (binuclear X Si-...
