Synthesis and structure of heterometallic chromium(III) complexes with ethylenediaminetetraacetic acid.

The ionic structures are composed of the [M(Tsc)2] 2+ cations and [Cr(Edta)]- anions with a component ratio of 1 : 2. The cation has a distorted trans-square coordination. The carboxyl groups of the H4Edta molecule are deprotonated and the ligand is attached to the Cr atom in the hexadentate chelating mode. The cations and anions are linked by a system of hydrogen bonds.enEngineering controlled terms Charge coupled devicescomplexationHydrogen bondsNegative ionsSuperconducting materialsSynthesis (chemical)Thermal effectsX ray diffraction analysis Engineering uncontrolled terms Chromium complexesEthylenediaminetetraacetic acid (EDTA)Oxide materialsWater bath Engineering main heading ChromiumArticle
