SYNTHESIS AND CHARACTERISTIC OF 2-HYDROXYPROPYLENE- 1,3-DIAMINETETRAACETOGERMANATES OF SOME s-METALS
Abstract
Differentmetal complexes of germanium (IV) and s-metals (Mg, Ca, Sr, Ba) with 2-hydroxypropylene-1,3-diamino-N,N,NI,NI-tetraacetic acid (Н5 Hpdta) are obtained for the first time and characterized by methods of elementary and X-Ray powder diffraction analysis, thermogravimetry, IR-specroscopy. By results of research by set of physical and chemical methods it is established, that obtained 2-hydroxypropylene-1,3-diaminetetraacetogermanates are complexes of cationic-anionic type: M[Ge(Hpdta(ОН(Н2О)]·nH2O, where M = Mg, n=9 (I); Ca, n=7 (II), Sr, n=7 (III); Ba, n=8 (IV). The scheme of structure of compounds I-IV is offered.
