Synthesis, Properties, and Crystal Structure of the Tin(IV) Complex with N-(2-Hydroxyethyl)ethylenediaminetriacetic Acid [Sn(μ-Hedtra)(μ-OH)SnCl3(H2O)] · 3H2O

摘要

The binuclear tin(IV) complex with N-(2-hydroxyethyl)ethylenediamine-N,N',N'-triacetic acid (H4Hedtra) is synthesized. The compound is characterized by elemental analysis, thermogravimetry, and IR spectroscopy. An X-ray diffraction analysis of complex Sn(μ-Hedtra)(μ-OH)SnCl3(H2O)] · 3H2O (I) is carried out. Structure I is formed by the binuclear complexes and molecules of water of crystallization. One of the tin atoms coordinates six "active" sites Hedtra~(4-) (the alcohol branch is deprotonated and forms a bridge between two tin atoms) and the bridging hydroxo group. The polyhedron is a pentagonal bipyramid. The octahedral environment of the second tin atom is formed by two bridging oxygen atoms, three chlorine atoms (fac isomer), and a coordination water molecule.
