Abstract

The interaction of germanium(II) chloride dioxanate with 3,6-di-tert-butyl-o-benzoquinone or with its mono-and dianion derivatives is attended by the redox transformations. The novel germanium bis-catecholate complexes were synthesized that contained coordinated ether molecules (THF (I), Et2O (II)) irrespective of the initial redox form of o-quinone. The germanium complex was also synthesized by the exchange reaction between GeCl4 and sodium catecholate. Complexes (I), (II) were characterized by NMR and IR spectroscopies, elemental and X-ray diffraction analyses.
