| Abstract | A series of novel pentacoordinated germanium(IV) complexes (I) has been prepared by the reaction of germanium dioxide with diols, such as 1,2-propanediol, 1,2-butanediol, 2,3-dimethyl-2,3-butanediol ,1-phenyl-1,2-ethanediol, 1,2-hexanediol, 3,3-dimethyl-1,2-butanediol in an aqueous sodium hydroxide medium. The general molecular formula can be represented as NaGe(OH)L2 where L is the deprotonated diol The reaction of germanium dioxide with catechol in distilled water gives Ge(C6H4O2)2.2H2O (II). Further treatment of this complex (II) with methanol, ethanol or 2-propanol gives hexacoordinated germanium (IV) complexes (III), Ge(C6H4O2)2.2ROH (where R = CH3, C2H5, (CH3)2CH, respectively). These complexes, which have been characterized by elemental analyses, thermogravimetric analyses, infrared, H-1 and C-13 NMR spectral studies, reveal that the pentacoordinated germanium(IV) complexes (I) have a slightly distorted trigonal-bipyramidal geometry. However, the suitable structure of the hexacoordinated complexes (II-III) are octahedral. |
