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

Abstract

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