GERMANIUM (IV) COMPLEXONATES WITH 2-HYDROXYPROPYLENE-l,3-DIAMINETETRAACETIC AND TRIETHYLENETETRAMINEHEXAACETIC ACIDS

Abstract

Methodologies worked out and: germanium (IV) complex with triethylenetetramine-N, N, NI, NII, NIII, NIII - hexaacetic acid (H6Ttha) - [(OH)Ge(p-Ttha)Ge(OH)]-2H2O (I), complex acid H2[Ge(Hpdta)(OH)(H2O)] H2O (II) and its compounds with inorganic cations Kat3[Ge(Hpdta) (OH)2]x2H2O (H5Hpdta — 2-hydroxypropylene-l,3-diamino-N, N, N’, N’-tetraacetic acid; Kat = Na (III), К (IV), NH4 (V)) have been synthesized. Individuality, composition and structure of the obtained coordination compounds is well-proven by the combination of research methods: elementary and X-ray powder diffraction analysis, thermogravimetry, infrared spectroscopy.
