Abstract

Onium bis(citrate)germanates (HNad)2[Ge(HCit)2] · 4H2O (I), (HIm)2[Ge(HCit)2] · 2H2O (II), and (HInd)2[Ge(HCit)2] · 2H2O (III) (where Nad is nicotinamide, Im is imidazole, and Ind is isoniazid) were synthesized by the reaction between bis(citrate)hydroxogermanic(IV) acid (H5O2)[Ge(OH)(H2Cit)(H2.5Cit)]2 · 2CH3COOH · 2H2O (H4Cit is citric acid) and organic bases. The complexes were characterized by elemental analysis, thermogravimetry, and IR spectroscopy. The X-ray diffraction analysis of complex I was performed. The structural units of a crystal of complex I were found to be centrosymmetric complex [Ge(HCit)2]2− anions, HNad+ cations, and crystallization water molecules.
