Description

Synthesis of transition metals compounds with bidentatus ligands derived from pyrazole, as well as pyrazole-lilamidine and 3(2-pyridil)pyrazole. Both ligands have an offshore aromatic system, which makes them interesting from the point of view of their physicochemical properties. In addition, they have an acidic hydrogen atom, which plays an important role when it comes to forming hydrogen bonds or easily deprotonated bonds, generating in both cases new polymetallic species of interest.The work being developed with these ligands consists of their coordination to metallic tricarbonilorenic(I) and bis(diimina)rutenic(II) fragments, with outstanding luminiscent properties. Some attractive applications are derived from these properties, such as its interesting bioinorganic chemistry, its cathalytic ability to reduce carbon dioxide, oxidate water or its activity in “fotorédox” processes. The reactivity of the synthesized complexes is based on the presence of acid hydrogen: anion identification or generation of polymetallic aggregates through the formation of hydrogen bonds, on one side, and the formation of new heteropolymetallic complexes, on the other side. In both cases, the compound synthesis is followed by the study of their luminiscent properties and their possible applications. On the other hand, these ligands compounds with the tricarbonylomanganesium fragment have possible applications such as carbon monoxide releasing systems in living beings. This safe and controlled emission has evident medicinal and therapeutic applications
