New 5-Chloro-Maleonitrile-Salen Ligand and Relative Co(II) Complex

Salen ligands and relative metal complexes are widely used in many fields, such as catalysis, sensing, optical electronic materials. The introduction of a wide range substituents different positions, both the salen scaffold diamine bridge, allows tuning chemical, catalytic spectroscopic properties. In this contribution, we report synthesis characterization new ligand Co(II) complex bearing maleonitrile bridge two chlorine atoms backbone.
