2-HYDROXYPROPYL-1,3-DIAMINTETRAACET AGERMANATICS:SYNTHESIS, PROPERTIES, STRUCTURAL FEATURES

Abstract

We generalized the experimental data and proposed optimal synthesis techniques and methods for growing crystals 25 homo- and heteronuclear complex of germanium (IV) and a series of s-, d-, f-metals with 2-hydroxypropylene-1,3-diamine-N,N,Nʹ,Nʹ-tetraacetic acid (H5Hpdta). Determined their spectral properties and thermal stability are described features of the structure. We compared characteristics of the synthesized 2-hydroxypropylene-1,3-diamine- N,N,Nʹ,Nʹ-tetraacetagermanatics depending on the electronic structure of the second metal. Have been discovered laws of formation on the basis of the complex anion [Ge(Н2О)(ОН) (Hpdta)]2– different types of supramolecular compounds: cation-anion, heterobinuclear and tetranuclear.
