What is it about?

Via an oxidation reaction of copper(I) iodide with a biologically active molecule, pyridine-2,6-dicarboxylic acid also known as dipicolinic acid, in DMF three copper(II) complexes were synthesized and characterized. In-situ DMF decomposition produces dimethylamine base under solvothermal conditions and a proton transfer reaction which is important for many chemical and biological reactions takes place for the complex formation of 1. Beside synthesis and characterization of new copper compounds, thermal and electrochemical properties were determined. Thermal decomposition of the complexes results in the corresponding metal oxides and electrochemical behavior of 1 can be explained as a metal-centered and diffusion-controlled, one-electron reduction process.

Why is it important?

New pyridine-2,6-dicarboxylatocopper complexes were synthesized using metal oxidation route and their structures were identified by single crystal X-ray diffraction and other common methods. One can find the ways to overcome the difficulties during the characterization of unknown and uncommon structures here.

Preparation of new compounds via metal oxidation-reduction routes, especially under solvothermal conditions, is a challenging alternative to prepare new compounds with different properties. This work clearly indicates the power of in situ metal oxidation route to prepare new compounds.
